Twenty-Toed Toad + Vigor + Star of Extinction

Twenty-Toed Toad

Vigor

Star of Extinction

How it works

1. Cast Star of Extinction by paying 5, destroying a land, dealing 20 damage to each creature your opponents control and each planeswalker, and putting twenty +1/+1 counters on each creature you control due to Vigor.
2. Declare Twenty-Toed Toad as an attacker, triggering its second ability, causing you to win the game.
