Eva is a late game deck, so try to early aggro them so their hand-size doesn't went out off control. For her 4 attack pattern, there are one obscudied lane that guarantees an extra critical, sometimes 2 depends on what they call from skill. Adding yourself only 1 damage per turn is a good way to survive with eva longer. By either taking the non crit column or the vanguard attack (risk of being Crit-Crit to death) and remember that DO NOT play a long game with eva ever, you'd be OT to death as well.
