Vraska the Unseen

Hi guys, today my card for you is Vraska the Unseen because she is fairly cheap at the moment. Vraska is a planeswalker with 5 loyalty, she costs 1 black, 1 green, and 3 any. Her card reads: +1: until your next turn, whenever a creature deals damage to Vraska the Unseen, destroy that creature.

-3: Destroy target nonland permanent.

-7: Put three 1/1 black Assassin creature tokens onto the battlefield with "Whenever this creature deals combat damage to a player, that player loses the game."
