I am looking for help with reviewing sets and/or maintaining Lore Seeker and the Big Custom Box. If you're interested, please contact me in #general in the Custom Standard Discord. —Fenhl
Artifact Creature - Shapeshifter
As Shapeshifter enters the battlefield, choose a number between 0 and 7.
At the beginning of your upkeep, you may choose a number between 0 and 7.
Shapeshifter's power is equal to the last chosen number and its toughness is equal to 7 minus that number.
Collector Number: 398
The ability that sets its power and toughness is a characteristic-defining ability. This means it applies before any other effects that modify power and/or toughness.
The ability that lets you choose a new number is a triggered ability that triggers only once each upkeep.
