Goblin Warchief

Creature - Goblin 2/2, 1RR (3)
Goblin spells you play cost {1} less to play.
Goblin creatures you control have haste.



Earwig Squad

Creature - Goblin Rogue 5/3, 3BB (5)
Prowl {2}{B} (You may play this for its prowl cost if you dealt combat damage
to a player this turn with a Goblin or Rogue.)
When Earwig Squad comes into play, if its prowl cost was paid, search target
opponent's library for three cards and remove them from the game. Then that
player shuffles his or her library.


要是場上有一隻Goblin Warchief，且已達成使用Prowl的條件

那請問我該支付2B或1B??

希望有善心人士幫忙解答，謝謝!! XDrz
