Ice Out

You may sacrifice only one artifact, enchantment, or token to pay a spell’s bargain cost.

If you copy a bargained spell, the copy is also bargained. If a card or token enters the battlefield as a copy of a permanent that’s already on the battlefield, the new permanent isn’t bargained, even if the original was.

Bargain means “As an additional cost to cast this spell, you may sacrifice an artifact, enchantment, or token.”
