This is exactly what the Jesmon deck needed to compete, albeit for a ridiculous price point
DESCRIPTION: Legendary Set
+ It may be a weak card, so you can make a card to trade one face down banish with the card on your opponent's field (Must be the same type of card, of course) + If it's a strong card, make a spell/trap that lets you summon it to your side of the field

it already count as Kaiju now to individual cards: Deep Sea: sac it self for search pretty decent Underground: it kinda like gamaciel if you dont get one, not the worst Smoke vs Volcano: these 2 are dilemma, Smokes is clearly inferior version of Volcano so you dont really want to run it
add 1 Level 5 or higher Zombie monster from your Deck to your hand, or, if "Zombie World" is in a Field Zone, you can Special Summon it from your Deck instead, also, in either case, you cannot Special Summon monsters for the rest of this turn, except Zombie monsters
