Sacred Mesa says "At the beginning of your upkeep, sacrifice Sacred Mesa unless you sacrifice a Pegasus." It also has an activated ability:

1W: Put a 1/1 white Pegasus creature token with flying into play.

My question is.. so let's say you use 2W to cast it. Then on your next turn you have your untap phase and your upkeep phase. Can you create a 1/1 white Pegasus token between your untap and upkeep phases to prevent Sacred Mesa's self-sacrifice clause from triggering?

    A general comment: there is never any "between" phases/steps. If there's an opportunity for anything to happen in the game, it's during a phase/step. (As for phase vs step, phases are subdivided into steps, e.g. the beginning phase has untap, upkeep, and draw steps.)

    Same goes for turns. It's always someone's turn.

Simple Answer

You can save Sacred Mesa by creating a Pegasus in response to Sacred Mesa's triggered ability.

Detailed Answer

Strictly speaking, you can't create a Pegasus between your untap step and your upkeep step because you don't have an opportunity to do so. The beginning of your turn has the following sequence of events:

  1. Your untap step:
    • You untap your permanents
  2. Your upkeep step:
    • Abilities that trigger at the beginning of the upkeep go on the stack
    • You gain priority.

You can only cast spells and activate abilities when you have priority, so the first opportunity to do so is during your upkeep, when the ability is on the stack though. This still lets you save your Mesa, though, because you can respond to the triggered ability by activating Mesa's activated ability. Because the activated ability went on the stack last, it will resolve first, and you will have your Pegasus before you need to sacrifice one.


You can save Mesa, but not in the way you specified.

You can't activate the ability before the triggered ability triggers, but you can save Mesa by creating a Pegasus in response to the Mesa's triggered ability.

  1. Mesa's triggered ability triggers as the Upkeep Step starts.
  2. Mesa's triggered ability is placed on the stack.
  3. In response, you activate Mesa's activated ability.
  4. Mesa's activated ability resolves:
    1. Put a 1/1 white Pegasus creature token with flying into play.
  5. Mesa's triggered ability resolves:
    1. You sacrifice the newly created Pegasus (or Mesa).
