I'd suggest having this attack twice each turn;
first spell damage, followed by physical.
Just saying how this could actually work in-game.
The card description should include how this gets extra stacks.
Why does this start of flying?
right now it's just a creature with potential to become a weapon.
I think the stacking mechanic is interesting,
they seem to have a hard time keeping up with psion, though:
without drawpower getting a spell every turn isn't really possible.
EDIT: do psions 'cast spells' or is it a creature attack with spell damage?
if they actually do cast spells, this does as well, and it is very OP.
I'd suggest making this a 'normal' weapon, and lowering the cost by 1.
also, how does this interact with adrenaline?
will every attack lower the charges by 1?
