Gamora

When Gamora enters the battlefield, destroy target creature.

Whenever Gamora attacks, surveil 1. (Look at the top card of your library. You may put it into your graveyard.)

Whenever a source your opponent controls destroys a creature you control, put a vendetta counter on Gamora.

Remove a Vendetta counter: Gamora gets +1/+0 and gains first strike until end of turn.
