Improvise is a keyword ability introduced in Aether Revolt. It is similar to Convoke, but uses artifacts instead of creatures. It allows a player to tap artifacts rather than pay some of the mana cost of a spell. Each artifact tapped after activating mana abilities pays for . Improvise is a fixed affinity for artifacts.[1][2]
Rules
Rulings
- Improvise doesn’t change a spell’s mana cost or converted mana cost.[3]
- When calculating a spell’s total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Improvise applies after the total cost is calculated.
- Because improvise isn’t an alternative cost, it can be used in conjunction with alternative costs.
- Improvise can’t pay for W, U, B, R, G, or C mana symbols in a spell’s total cost.
- You can use artifacts with summoning sickness.
- Improvise can’t be used to pay for anything other than the cost of casting the spell. For example, it can’t be used during the resolution of an ability that says “Counter target spell unless its controller pays 3.”
- If an artifact you control has a mana ability with T in the cost, activating that ability while casting a spell with improvise will result in the artifact being tapped when you pay the spell’s costs. You won’t be able to tap it again for improvise. Similarly, if you sacrifice an artifact to activate a mana ability while casting a spell with improvise, that artifact won’t be on the battlefield when you pay the spell’s costs, so you won’t be able to tap it for improvise.
- When using improvise to cast a spell with X in its mana cost, first choose the value for X. That choice, plus any cost increases or decreases, will determine the spell’s total cost. Then you can tap artifacts you control to help pay that cost. For example, if you cast Whir of Invention (a spell with improvise and mana cost XUUU) and choose X to be 3, the total cost is 3UUU. If you tap two artifacts, you’ll have to pay 1UUU.
- Tapping an artifact won’t cause its abilities to stop applying unless those abilities say so.
- Equipment attached to a creature doesn’t become tapped when that creature becomes tapped, and tapping that Equipment doesn’t cause the creature to become tapped.
