Kai'Sa in Riftbound
Kai'Sa has 1 Legend, 1 Signature card and 2 champion units in the released Riftbound sets. Here is every one, what it does, and how they fit together in a Kai'Sa deck.
Kai'Sa's Legend
A Kai'Sa deck is led by Kai'Sa, Daughter of the Void, which plays Fury and Mind. The Legend is the card that leads your deck: its tag names your champion and its two domains are the only ones your other cards can come from.
| Card | Set | Domain | Rules text |
|---|---|---|---|
| Kai'Sa, Daughter of the Void | Origins | Fury and Mind | [Exhaust]: [Reaction] — [Add] [Any Power]. Use only to play spells. (Abilities that add resources can't be reacted to.) |
Text is as Riot's card gallery gives it, with icons in brackets: [1] is 1 Energy, [Any Power] is 1 Power of any domain and [Exhaust] means turn the card sideways. Every Riftbound Legend →
Kai'Sa's Signature cards
Kai'Sa has 1 Signature card. A Signature card carries one champion's tag, and only a deck whose Legend names that champion can play it. Your deck can hold at most 3 Signature cards in total, counting copies.
| Card | Set | Type | Domain | Cost | Rules text |
|---|---|---|---|---|---|
| Icathian Rain | Origins | Signature spell | Fury and Mind | 7 | Deal 2 to a unit. Deal 2 to a unit. Deal 2 to a unit. Deal 2 to a unit. Deal 2 to a unit. Deal 2 to a unit. |
Kai'Sa's champion units
Kai'Sa has 2 champion units across 1 set. One copy of a champion unit sits out as your Chosen Champion, which must carry your Legend's tag, so these are the cards a Kai'Sa deck picks it from. Each has its own name, and the 3-copy limit counts each name apart.
| Card | Set | Domain | Rarity | Cost | Might | Rules text |
|---|---|---|---|---|---|---|
| Kai'Sa, Survivor | Origins | Fury | Epic | 4 | 4 | [Accelerate] (You may pay [1][Fury] as an additional cost to have me enter ready.) When I conquer, draw 1. |
| Kai'Sa, Evolutionary | Origins | Mind | Rare | 6 | 6 | [Ganking] (I can move from battlefield to battlefield.) When I conquer, you may play a spell from your trash with Energy cost less than your points without paying its Energy cost. Then recycle it. (You must still pay its Power cost.) |
Building aKai'Sa deck
A Riftbound deck has 1 Legend, a main deck of at least 40 cards, 12 runes and 3 battlefields. Every card in the main deck has to come from your Legend's two domains, which decides which of Kai'Sa's cards each Legend can use.
| Legend | Domains | Chosen Champion options | Signature cards in its domains |
|---|---|---|---|
| Kai'Sa, Daughter of the Void | Fury and Mind | Kai'Sa, Survivor, Kai'Sa, Evolutionary | Icathian Rain |
A champion unit can be your Chosen Champion only if every domain it has is one of your Legend's two. Units of other champions can still go in your main deck as ordinary cards if their domains fit. The full deck-building rules → Published Riftbound decks →
