Graydle Kaiju is a surprisingly flexible control deck with the aim of Tributing your opponent's monsters with Kaijus and then taking control of them with the Graydle monster's effects. Having Kaiju's in the main deck provides one with a much-needed answer to monsters that you simply cannot run over.
3 copies of Interrupted Kaiju Slumber allow for us to get the ball rolling early when going second, generally you'll want to have Jizukiru on your side and give your opponent Gameciel when resolving Slumber. The other Kaiju's are there as a backup. The deck would like to go second, as going first is far to slow and this deck does not make an impactful board unless it has it's Graveyard loaded up since you can Synchro Summon using Slime Jr.
Rebellion is as an extra layer of defense that can mean the difference between life and death in some situations, it's a very helpful Battle Phase trick. For consistency, we have Graydle Impact, Pot of Avarice, and Salvage. The latter two cards reload our deck and hand respectively while Graydle Impact provides consistent searching during the End Phase as well as the ability to tutor for another Graydle as well as clearing cards off your opponent's board.
The Extra Deck contains some normal Link goodstuff as well as some Water synchros that we have to make due to the restriction that comes with Slime Jr's effect. Edit these ratios as you see fit. :)
For the side deck, a Mild Turkey is a must! Add whatever you want to make up the other 14 cards.
