Whenever you put one or more counters on a Goblin, Orc, or Army you control, The Great Goblin deals 2 damage to target opponent.
Whenever another Goblin, Orc, or Army you control dies, exile the top card of your library. You may play it until the end of your next turn.
You pay all costs and follow all timing rules for cards played this way. For example, if the exiled card is a land card, you may play it only during your main phase while the stack is empty and only if you have an available land play remaining.
