Powers

There are 3 different types of Powers; Payment, Triggered, and Continuous. Payment powers are identified by the arrow that separates the cost of the power and the effect the power puts on the chain. Triggered powers are identified by the words "at the start of," "when," or "whenever." Continuous powers create continuous modifiers and do not use the chain.

Payment Powers
- Unless specifically stated otherwise, only an object's controller can use its payment powers.

- Unless specifically stated otherwise, a player may use a payment power at any time he or she has priority, as long as that player is able to pay the associated cost. A player can't use a payment power unless he or she has the means to do so. A player may use a given power more than once sequentially if he or she can pay the cost each time, since that player gets priority again after each time the power is used.

- A card's restrictions on the number of times a payment power may be used apply only to that card and that power, not to other cards that may have the same name. These restrictions are written as "Use only per ."

Triggered Powers
- Some triggered powers trigger off an event and have an additional trigger condition. That condition is checked only upon triggering and not upon resolution.

- Some triggered powers have a conditional effect. The effect's condition is checked only upon resolution and not upon triggering.

- Some triggered powers have a conditional clause immediately after the trigger event, set off by commas. Such powers are called "double-check" powers. A double-check power triggers only if it's condition is true. Its effect is negated if its condition is no longer true on resolution.

Continuous Powers
- Any power that is not a payment power or a triggered power is a continuous power.
