Muddle, the Ever-Changing fuels a spellslinging strategy where casting instants and sorceries repeatedly transforms it into a copy of another creature with myriad, flooding the board with attacking tokens that trigger powerful enter-the-battlefield and combat effects. The deck supports this loop with cheap cantrips, bounce spells, and haste enablers to maximize how often Muddle can copy key creatures in a single turn, generating value through card draw, treasure production, and damage. The primary win conditions are infinite token and combat loops using Dualcaster Mage with token-doubling spells or Rionya, Fire Dancer paired with Combat Celebrant to generate endless attack phases.
