  1. Bug description
    Buffed Ulti-Apelio at 3200 ATK dying when I attack BlueEyesAltDragon
    The AltDragon was used by a bot if that makes a difference

  2. Bug reproduction steps
    Use base Apelio’s effect to banish from GY and buff, then summon UltiApelio and attack the enemy BlueEyesAltDragon, then watch your Ulti-Apelio die

  3. Screenshot OR error code
    unfortunately, none

  4. Expected behavior
    The enemy BlueEyesAltDragon should have died
