Duchess, Virtuous Thief

Duchess can’t be blocked by creatures with greater power.

Whenever Duchess deals damage to a creature or player, put a charge counter on this creature. This ability triggers only once each turn.

{3}: Duchess deals damage to target creature or player equal to the damage already dealt to that creature or player this turn.

Finale - Remove three charge counters from Duchess: Creatures you control gain hexproof and can't be blocked until end of turn.
