Bargain

Bargain is a keyword ability introduced in Wilds of Eldraine that allows you to sacrifice an artifact, enchantment, or token as you cast the spell for an additional effect. 
==Description==
Bargain is a variant of Kicker, with a fairytale flavor. A spell has been bargained if its controller declared the intention to pay any or all of its bargain costs. Like Kicker, Bargain uses an additional cost to enable a linked ability, so its actual effect is completely open-ended.
One effect that is usually left off kicker is cost reduction, even though the rules can handle such a result. Bargain has this in cases like <c>Ice Out</c> and <c>Hamlet Glutton</c>.
<c>Lich-Knight's Conquest</c> and <c>Malevolent Witchkite</c> have the Multikicker equivalent of Bargain. <c>Devouring Sugarmaw</c> asks for a Bargain every upkeep.
==Rules==
==Rulings==
*Bargain represents an optional additional cost. A spell cast with that additional cost paid is "bargained."
*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.
*Some instant and sorcery spells require additional targets if they're bargained. You ignore those targeting requirements if those spells aren't bargained, and you can't bargain those spells unless you can choose the appropriate targets.
**On the other hand, you can bargain a permanent spell even if you won't be able to choose targets for an enters-the-battlefield ability of that permanent once the spell resolves.
