The Sisters

Every other Leader starts at 20 health; The Sisters start at 15. Once per turn, on your turn, removing an entity from your opponent’s Garden with a card effect lets you play a weapon from your hand or discard pile, as long as its cost is no higher than the removed entity’s base cost.

Water brings the removal (bounce, and the new displace), Lightning brings the weapons and the ways to refill the discard pile with them. Azuki says the dual-element Leader can choose from six Water and Lightning Gates, which no deck could do before.

The printed subtypes are Raizan and Shao. Ikazuchi checks whether the card holding it has the Raizan subtype, so it works when equipped to The Sisters. Shao’s Perseverance says “If your leader is (Shao)”, which should count too, pending an official ruling.

With the full set out, the cheap removal that turns them on is Puddle Abduction (2 IKZ, displace cost 4 or less), Waterthread Bracelet (1 IKZ, cost 1 or less), Lowtide Jack on a portal, and Vessel of Mizuryuu. Lightning’s new 1-cost weapons (Stormlink Beads, Overcharge Shiv, Killing Song, The Wooden Fish) are the easy plays off a 1- or 2-cost removed entity.
