This is only (and rare used) in dark magician deck. Also it is a double knife card. Can also hurt you if you don't use it correctly. There are TONS of other cards that scream for limitations. This card is a joke in comparison to them.
with new support survivals end might this card see play again?
try to keep your deck at 20 cards to minimize your odds.
you should add Sergeant Electro, Metalmorph, and Windstorm of Etaqua.
Remove the Jammers and fossil excavation and remove 3 cards that wont help you. personally i would remove the polymerizations and that fusion equip spell. and if you have a order to charge use that instead of the greed of shard.
and you will have a good meta
you need at least 50% beatdwon mobs, and 60% to make it balanced, so 10-12 mobs + 8-10 supports, I rather got 3-3-3 dinosaur- 2 any other normal like dunames and jerry OR 2 sargent electro so you can buff your element saurus, total 11 mobs, 1 kuriboh, 1 mirror, 1 metalmorph, 1 de-spell for pvp mai, 1 twister for mai again, 2 order to charge and 2 econs if you carry extra normal
and change otc for 2 more metalmorph if you carry sargent electro (which I rather to get since sargent gives a looot of support not just for his op ability but the 500 extra dmg on element is way too good even if they 🔥 your field
For idk reason, I never see this card in ranked vs dino decks. Either leveling rex to 33 is to much work or this card is just isn't useful.
