• During your opponent's Battle Phase: Your opponent gains 1000 LP, then end the Battle Phase.
• When your opponent activates a monster effect, while they control more cards than you do: Special Summon 1 "Red Dragon Archfiend" or "Hot Red Dragon Archfiend" from your Extra Deck or GY, and if you do, negate that effect, and if you do that, destroy that card.
