Goblin Roullette

Minion Offering (When you cast this card, you
may sacrifice a token creature in addition to its cost)
If you sacrificed a goblin as you cast Goblin Roullette, add {r} to your mana pool.
Each player discards a card at random. If any player discards a land card this way, put Goblin Roullette into your hand instead of your graveyard as it resolves.
