Strategy

1

Sleep turns are your setup window — play Powers, scaling cards, and buffs for free.

2

Plating 12 reduces all damage while asleep. Multi-hit attacks help pierce it.

3

Soul Siphon permanently drains your Strength and Dexterity. Kill fast or get overwhelmed.

4

Poison, Doom, and non-Strength scaling ignore her stat drain.

5

If you have strong scaling, let her sleep all 3 turns. If you need to race, wake her early.

6

Block builds are safer here since they don't rely on Strength that gets drained.
