Goblin Unification

When Goblin Unification enters the battlefield,
search your library for any number of Goblin
cards and reveal them. Shuffle your library, then
put those cards on top of it in any order.
Goblin creatures you control get +1/+1 for each
Goblin card revealed this way.
Their squabbling days were over. The time of the
unified goblin horde had just begun.
