Instead of Ultra Evolution Pill, I'd add metamorphasis to show the mutation of the turtles. Then I'd throw Goblin ATK Force to represent the turtles( Well, it sorta looks like them), and then I'd add in the card with the motorcycle, I think It's called gurstaph Gustrider or something, for the shell cycles.

lol this deck is mad funny homie, and happy 1000th post homie

I think I like Ultra Evolution Pill better, because it looks kinda like the container of ooze from the second movie. I think monsters that are turtles would better represent the turtles (call me crazy...). I will add the Chaosrider though.

Maybe Overdrive for that van they used in the cartoon?? lol

Dunno if it's been mentioned but since they started out as turtle's, we could have Turtle's in the Deck too
