This creature gets +2/+0 for each other Goblin you control.

At the beginning of combat on your turn, target creature you control with a +1/+1 counter on it gains menace until end of turn. (It can't be blocked except by two or more creatures.)
Exhaust — : Put two +1/+1 counters on this creature. (Activate each exhaust ability only once.)

Flying

At the beginning of your first main phase, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.)

Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.)
Whenever this creature deals combat damage to a player, that player loses life equal to the number of creature cards in your graveyard.

Lifelink (Damage dealt by this creature also causes you to gain that much life.)
When this creature dies, each player mills three cards. (They each put the top three cards of their library into their graveyard.)

Trample

• Bring Down — Destroy target creature with flying.

At the beginning of combat on your turn, you may blight 1. When you do, target creature gains haste until end of turn. (To blight 1, put a -1/-1 counter on a creature you control.)

Whenever you cast a noncreature spell, amass Goblins 1. (Put a +1/+1 counter on an Army you control. It's also a Goblin. If you don't control an Army, create a 0/0 black Goblin Army creature token first.)
