Neriv, Crackling Vanguard

[[ keyword: "Flying" ]], [[ keyword: "deathtouch" ]]

When Neriv enters, create two 1/1 red Goblin creature tokens.

Whenever Neriv attacks, exile a number of cards from the top of your library equal to the number of differently named tokens you control. During any turn you attacked with a commander, you may play those cards.
