Another mock-up of Trident Dragion basically. The card is kind of slow by itself, but I didn't bother to read the support, but I'm sure it's just things to make it more consistent. Does it work with vanilla monsters? It sounds like it does.

Its not an [i]exact[/i] Trident Dragon, but I see your point.
Mostly, I just thought it would be neat if a monster would be able to mutate/evolve/what-ever into another one, through different means.

Yea, the other stuff are just cards to speed it up.
Though, I could make it Summon itself from more counters, and have it work where the if the monster just battles, instead of having to declare an attack, to potentially speed it up even more.
Oh, and Junk Synchron can revive Normal Monsters, despite the fact he negates effects regardless.
