Copying Spells

[MetalMadMan]

If I cast goblin grenade and cast a spell that copies that spell do I have to sacrifice another goblin?

[BadLuckIrish]

If I cast {goblin grenade} and cast a spell that copies that spell do I have to sacrifice another goblin?

use curly brackets on cards.

And no. The saccing is a cost then the grenade goes on the stack. Then u cast say {Increasing Vengence} itll copy the spell but its payment is done. If u played a spell with mana of X, that is also copied
