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

[Dragonstrike]

Additional note to your edited orders, @Mikaruge108: if you want to test how effective Sheer Cold is, I'd highly recommend using it first instead of second.  And then if it turns out that it can indeed harm Deoxys to some degree without the Sword, then put in some conditional orders to keep using Sheer Cold.

Otherwise, using moves that can Flinch, Freeze, and Burn Deoxys (particularly Burn 2 and 3) are going to be the most helpful ones if they aren't being powered up by the Sword (assuming the Helm's effects haven't been shifted).
