LIGHT / Pudgyville Pony-Type Xyz / Rank 3 / ATK 0 / DEF 2000
2 Level 3 monsters
Once per turn, during either player's turn: You can target up to 2 cards on the field; treat them as a different type of card (Monster, Spell or Trap). (If you treat Spell/Trap Cards as Monster Cards by this effect, they are treated as Level 1 monsters with 0 ATK and DEF.) If this card has "My Pudgyville Pony Silly Pie" attached to it as Xyz Material, it gains this effect.
● You can detach 1 Xyz Material from this card, then target 1 card on the field that is not its original (printed) card type; banish that target.
