[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Spiritmon]

Spoiler

This isn't as freeform as you're thinking, Spirit.  We're still bound by the TMs that canonically exist in the main series games and Uranium.  If it isn't a TM in any of those games, it isn't a TM we can pick out here at all.

Of the ones you listed, the only eligible ones are Shadow Claw, Giga Drain, and Icy Wind.  And Shadow Claw can't be taught to Doublade unless Iron's approved if already because it isn't on Doublade's movelist in the book.
