Rule 118.10 · Costs

Each payment of a cost applies to only one spell, ability, or effect. For example, a player can’t sacrifice just one creature to activate the activated abilities of two permanents that each require sacrificing a creature as a cost. Also, the resolution of a spell or ability doesn’t pay another spell or ability’s cost, even if part of its effect is doing the same thing the other cost asks for.
