REI Build Guide

Rei is a conditional buffer who trades flexibility for raw power. Her cards grant enormous temporary bonuses—like 100% increased damage—but only to specific card types (e.g., Basics or 1-cost cards). This makes timing and deck planning crucial to extract full value. Rei can also thin her hand by exhausting cards for draws, maintaining flow and precision. When used well, she amplifies team damage to absurd levels while contributing solid support and Tenacity damage herself.
