The Silent
A huntress from outside the Spire. Ready to stab and poison anything in her way.
Sly cards play for free when you discard them from your hand during your turn, so Acrobatics, Prepared and Calculated Gamble turn a hand into free plays and Energy. The end-of-turn discard doesn't count. Tingsha and Tough Bandages pay you for every discard. Thin the deck of non-Sly cards or it falls apart.
TingshaUncommon3 damage to a random enemy per card you discard on your turn. Every cycle card is now an attack.
Tough BandagesRare3 Block per discard on your turn. Block and damage from the same discards.
