Malefic Claw Stream X TRAP Activate only if you control a face-up "Malefic" monster

Outside of this, I dont see any of these cards leading decks in their own right, which is a shame given how iconic these characters are

Extra Deck 4 Alligator's Sword Dragon X WIND Level 5 [ Dragon / FusionEffect ] ATK 1700 DEF 1500 "Baby Dragon" + "Alligator's Sword" This card can attack your opponent directly if the only face-up monsters they control are EARTH, WATER, or FIRE

return that monster to the hand, and if you do, Special Summon this card, but banish it when it leaves the field
