Onslaught — Rare
Creature Goblin Warrior
Protection from blue (This creature can't be blocked, targeted, dealt damage, or enchanted by anything blue.)
Whenever Goblin Piledriver attacks, it gets +2/+0 until end of turn for each other attacking Goblin.
Throw enough goblins at any problem and it should go away. At the very least, there'll be fewer goblins.
