When a player's Deck Master leaves the field (if playing using "Deck Master" rules)

UR Ultra Rare Jigen Bakudan X FIRE Level 2 [ PyroFlipEffect ] ATK 200 DEF 1000 FLIP: After this card is flipped, offer it as a Tribute during your Standby Phase to destroy all monsters on your side of the field and inflict Direct Damage equal to half of the total ATK of the destroyed cards (excluding this monster) to your opponent's Life Points

The biggest downside to this card is that you need to Tribute Summon it using five Monsters, which eats up resources and uses up your Normal Summon

Master Ball is essentially Number 11 in Spell Card form
