Activate 1 of these effects (but you can only use each effect of "Infernal Punisher" once per turn);
• Add 1 WATER Dinosaur monster from your Deck to your hand, then you can Special Summon it if your opponent controls a monster.
• Tribute 1 monster; Special Summon 1 Level 6 or higher FIRE monster from your hand, Deck, or GY, but negate its effects if it is a non-Fiend monster.
