BargainBargain is a static ability that functions while the spell with bargain is on the stack. “Bargain” means “As an additional cost to cast this spell, you may sacrifice an artifact, enchantment, or token.” Paying a spell’s bargain cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.
If a spell’s controller declares the intention to pay that spell’s bargain cost, that spell has been “bargained.” See rule 601.2b.
Objects with bargain have additional abilities that specify what happens if they were bargained. These abilities are linked to the bargain ability printed on that object: they can refer only to that specific bargain ability. See rule 607, “Linked Abilities.”
If part of a spell’s ability has its effect only if that spell was bargained and that part of the ability includes any targets, the spell’s controller chooses those targets only if that spell was bargained. Otherwise, the spell is cast as if it did not have those targets. See rule 601.2c. (CR 702.166) (You may
sacrificeTo sacrifice a permanent, its controller moves it from the battlefield directly to its owner’s graveyard. A player can’t sacrifice something that isn’t a permanent, or something that’s a permanent they don’t control. Sacrificing a permanent doesn’t destroy it, so regeneration or other effects that replace destruction can’t affect this action. (CR 701.21) an artifact, enchantment, or token as you
castTo cast a spell is to take it from the zone it’s in (usually the hand), put it on the stack, and pay its costs, so that it will eventually resolve and have its effect. A player may cast a spell if they have priority. See rule 601, “Casting Spells.”
To cast a card is to cast it as a spell. (CR 701.5) this spell.)
Torch the Tower deals 2 damage to target creature or planeswalker. If this spell was bargained, instead it deals 3 damage to that permanent and you
scryTo “scry N” means to look at the top N cards of your library, then put any number of them on the bottom of your library in any order and the rest on top of your library in any order.
If a player is instructed to scry 0, no scry event occurs. Abilities that trigger whenever a player scries won’t trigger.
If multiple players scry at once, each of those players looks at the top cards of their library at the same time. Those players decide in APNAP order (see rule 101.4) where to put those cards, then those cards move at the same time.
An ability that triggers whenever a player scries triggers after the process described in rule 701.22a is complete, even if some or all of those actions were impossible. (CR 701.22) 1.
If a permanent dealt damage by Torch the Tower would die this turn,
exileTo exile an object, move it to the exile zone from wherever it is. See rule 406, “Exile.” (CR 701.13) it instead.
