Move Creation Workshop

[Amaterasu]

Sonny (Alternate Form) I wouldn't even put the disadvantages into it. Alt forms have a pretty clear set of rulings, if you give them a disadvantage it'll be fluff and little more. Of course, if you want to do it go ahead.

T1 Super Defense: Two Bodies, One Mind The alt form swap is allowed, as far as I know. I remember Arty doing something to that effect when she submitted DVa and her T1 Super Attack, forcing her to swap from mecha to pilot form and vice versa.
Although, the move description is a little confusing. I don't see when the new permanent body is created and the temporary body is left behind. Just keep in mind that an outsider needs to be able to understand this easily when reading it.

Sun and Parhelia I have no idea if it is okayable to have the "curse" feed off of other people's stamina, though seeing how they can just disable it at a moment's notice I don't think that it should be a problem. Everything else looks good, I can see no errors.

T1 Super Defense: High Pressure Shield8 seconds sounds awfully long since it's a Super Defense, reacting to a Super Attack typically. You could probably reduce it to less. The ability of materializing a shield around an ally would bump the cost up though.

Two Bodies: The new body is created and the old body acts as a shield, taking the attack, which is why its left behind. Hopefully that helps clear up confusion.

High Pressure Shield: Lowered to 4 seconds. How much would the cost be bumped up though?

Right, that makes more sense. And for the High Pressure Shield, I'm starting to doubt my own words actually - it may be that you have to pay 2x (so 1200) for the ability to materialize it around other people, but on the other hand the shield is doing the same thing, it's just summoned at a different location. I think that that alone wouldn't bump the cost up. I'm not 100% positive on this though. The MA staff will probably know better
