Legends of Runeterra (LOR) Cosmic Creation: All about the new expansion

A new expansion arrives!

Riot Games just revealed the new expansion for Legends of Runeterra, named Cosmic Creation. This should be the last expansion for Call of the Mountain. It will come out on December 16. In this Legends of Runeterra Cosmic Creation article, we will be listing the cards as they are revealed along with a small review of each and every card.

Legends of Runeterra Cosmic Creation New Keyword: Augment

Legends of Runeterra Cosmic Creation

This new keyword is incredibly versatile. You can use it with Gems, Celestials, and champions who generate cards like Draven, Heimerdinger, and Lux. The effect itself is quite simple as it just provides +1 to power. For now, it seems like a Piltover and Zaun exclusive keyword. We’ll have to see.

New card types in Legends of Runeterra Cosmic Creation

Mechanized Mimic

Legends of Runeterra Cosmic Creation

The first card revealed is Mechanized Mimic. This seems like the type of card you’d build a deck around for potential combo finishers. Giving it things like Overwhelm, Elusive, and even Double Attack. Or all of the above.

Calculated Creations

This card for the Legends of Runeterra Cosmic Creation expansion is reminiscent of Behold the Infinite as both cards cost 2 mana and give you a choice of three cards. In Calculated Creations case, it will always be the same three cards. It’s important to note that these three cards are not linked to Calculated Creations and will be reviewed below. As for Calculated Creations, it’s simple, if Augment decks become a thing, it’s very likely this card will be included.

Ballistic Bot

This is a solid card on its own. It’s probably the better choice of the three cards offered in Calculated Creations. It continues to provide value each round and can help other Augment cards grow.

Armed Gearhead

The 1 health certainly holds this card back. It’s still a respectable card, though. It’s kind of like a small Fae Bladertwirler, except presumably easier to grow in strength.


Legends of Runeterra Cosmic Creation

3 mana 1/3 is a terrible statline. But Elusive and Augment on the same card is pretty scary. In a lot of circumstances, this card could finish the game on its own, but it’ll probably not do much against control decks with powerful removal and stall.

Hexcore Foundry

A great card for combo decks especially. It might not see play if the meta is too aggressive. Giving aggro decks free fuel is dangerous.


Legends of Runeterra Cosmic Creation

4 mana and slow… but it can target anything or destroy a Landmark. This card is very difficult to evaluate, but being able to deal 3 to the enemy nexus is nothing to scoff at. Definitely keep an eye on this one.


The Piltover and Zaun champion is here in the Legends of Runeterra Cosmic Creation expansion and he’s a strange one! 4 mana 2/4 is a pretty bad statline (mostly on the power) but he has Augment which will allow you to fix that problem. But he technically has more than just Augment – every Round Start he will create a Hex Core Upgrade which grants him a random keyword.

He seems to lean on a midrange/control style of play. This means he has a decent chance at impacting the meta as it is a bit heavy on the aggro right now.

Death Ray and Iterative Improvement

Death Ray is definitely going to be a staple in Viktor decks, possibly with Ezreal as well. You could even combine it with Funsmith. This card has a lot of potential, although a deck with this card might want to run a lot of draw.

As for Iterative Improvement: it’s a neat card – goes well with Augment cards and Viktor. But 2 mana is pretty expensive… but with a leveled up Viktor, the copied unit would be cheaper. Hard card to evaluate until used in play.

Monastery of Hirana and Boomship

Monastery of Hirana is the first Ionia Landmark we see. It’s a very bizarre one too as it continuously creates Sanctuary cards which let you recall units at burst speed but cannot be used in combat or in response to a spell. There’s definitely some combo potential here but we’ll have to see the rest of the cards to determine how valuable this is.

Boomship is a nice addition to the Powder Keg archetype. By itself it’s a pretty mediocre card, but in a deck built around it, maybe with Funsmith, it has the potential to be good.

The Scargrounds, Homecoming, and Wiggly Burblefish

The Scargrounds is incredibly exciting! It might be the card to finally make the self-damage archetype viable. Gaining +1/+0 along and Tough is nothing to scoff at!

Homecoming, on the other hand, might not be too great. You can easily stop that effect from happening. This one seems like a meta dependent tech card, or perhaps there will be more cards that benefit from recalling units.

Wiggly Burblefish is one of the weirdest cards released to date. A 6 mana 3/1 with Elusive that can be discounted by casting spells. Well, the best case scenario would be to make this 0 cost. So is a 0 mana 3/1 with Elusive powerful enough? Not by itself, but if buffed through means like Omen Hawk or even Mind Meld then maybe.

It That Stares

Another big unit for Freljord. Could possibly find a home in ramp decks but the competition in those is fierce. But an 8 mana 8/8 that comes with essentially an Avalanche, along with the utility of destroying Landmarks is a little crazy. This card will see play if the meta finds itself with aggro decks that have a lot of low health units or decks that rely on Landmarks.

Pesky Specter, Evershade Stalker, and The Grand Plaza

Pesky Specter is pretty exciting! We’ve never had a card that disrupts the enemy in this way. The card might not be as bad as you think. It’s good for activating Nightfalls or effects that require a friendly unit to have died.

Evershade Stalker, however, looks kind of bad. This card seems to be designed as an ”infinite” card. If you continue to summon it with its Nightfall effect activated, you’ll continue to generate Evershade Stalkers. But a 2/2 that can’t block isn’t very powerful at all…

It could potentially work for Hecarim, Nocturne, and Diana. All three of these champions could level up pretty quickly with Evershade Stalker.

The Grand Plaza is the first Landmark card for Demacia and it’s scary. Giving a unit +1/+1 and Challeneger, even for one round, is incredible. This card could go great in dragon decks or just any midrange Demacia deck that aims to control the board via combat.

Solari Sunforger, Moonlight Affliction, and Targon’s Peak

Solari Sunforger seems like an okay card but isn’t very interesting. Targon already has good healing. If it were a 4/5 instead of a 5/4 it’d have more potential.

Moonlight Affliction looks like a powerful card already. Similar to Hush! but this card targets two units and can even prevent them from blocking.

Targon’s Peak is another Landmark card for Targon that funnily enough looks like it would fit better in Freljord. This is definitely more of a ramp card than anything else. Fill your deck with high costed units and watch them become 0 cost. Careful, though, your opponent will get the same benefit.

Captain Arrika

This is a solid card, no doubt. The stats aren’t that bad and she captures a unit or Landmark upon being played which kind of makes up for it. Not only that, but she has Spellshield, making it harder for your opponent to disrupt her. It’s hard to see where she’d fit in in the current Demacia decks, but perhaps she’ll enable a new Elite deck of some kind.


Zoe is as chaotic as one would expect in the Legends of Runeterra Cosmic Creation expansion. Her level up could lead to some insane combos and finishers. However, levelling her up is quite the task. Not only does Zoe have 1 health but her level up requirement needs her to be on the board, meaning you can’t level her up while in hand.

Thankfully, she has Elusive and a helpful Nexus Strike. She’ll have to pair with a region that can keep her protected.

Spell Thief and Supercool Starchart

Spell Thief looks downright crazy. It’s almost like a Nab effect, except you get to pick what you want. Much like Nab this card could lead to some annoying losses.

Supercool Starchart doesn’t look all that great but good pair well with the likes of Viktor.

Sleepy Trouble Bubble and Paddle Star

Sleepy Trouble Bubble would be bad on its own, but it does create a Fleeting Paddle Star that could potentially get rid of a threat. The card could also go well in Leona decks and Yasuo decks. As for Paddle Star, it is a slightly easier to execute but worst Ravenous Flock. Paddle Star will likely still see play because dealing 4 damage for 3 mana is still a good deal.

Starry Scamp and Sparklefly

Starry Scamp is reminiscent of Claws of the Dragon. It’s not bad – 0 mana 2/2 is definitely playable.

Sparklefly is trickier to evaluate. Elusive and Lifesteal are both great keywords but not so much on a 2 mana 1/2. It could go well with leveled up Zoe or with hand buffs. Even Taric could find a way to make this card shine.

Hunt the Weak and Brutal Hunter

Hunt the Weak has a very unique effect that forces your opponent to discard something. Looks more like a tech card that you’d include in very specifics meta. It’s possible the Noxus champion will benefit from this in some way.

Brutal Hunter has a very powerful combination of keywords when summoned: Challenger and Quick Attack. This could be very handy in a midrange deck – especially against aggro decks.

Wrathful Rider and Arrel the Tracker

Both of these truthfully look atrocious. 5 mana for 7/3 in stats is not the dream, even if it does have Challenger. Arrel the Tracker’s effect does have solid potential but at 6 mana with such low power… We’re going to have to wait for the last batch of cards to (hopefully) make sense of these.


Riven is as fearsome as the fans wanted her to be. Her level 1 form has premier stats for the mana cost (Loyal Badgerbear stats) and she generates a card at least every attack turn. Her level 2 form is even scarier if you give her Overwhelm or Elusive. It’s hard to see a world where Riven isn’t at the very least viable.

Blade Squire, Runeweaver, and Weapon Hilt

Reforge is the new keyword which creates a random blade fragment. Blade Squire and Runeweaver seem pretty good, but Weapon Hilt is lacking a bit.

Glinting, Keen, and Heavy blade fragments

All three have the same text as gems. Meaning despite being burst speed, they cannot be used in combat or as a response to a spell. They are about at the same power level though you could argue the Heavy Blade Fragment is the superior one, as Overwhelm can close out a game.

Blade of the Exile

If you cast all three blade fragments, you get the Blade of the Exile. An insane slow speed buff card. There’s not much to say other than it’s worth it.

Sharpened Resolve

It’s a bit underwhelming but not too bad. It might find a home somewhere because Noxus doesn’t have much in the way of stat changing cards.

Survival Skills

Discard support is unexpected but welcome. This card can still most certainly be used outside of discard decks. It could go great in self-damage decks like Vladimir. We’ll see.

That’s all the cards released for the Cosmic Creation expansion in Legends of Runeterra. As new cards keep getting released, we’ll keep updating this article!
