I do not have one, but I have always wondered, can you change its form several times like Rotom? Also if you teach it a move in one form that it can not learn in another then do you keep the move upon form changing? Example: Deoxys(A) learns Zap-cannon, if I change it to Deoxys(S) will it keep Zap cannon.
Q1: Yes, you can change formes as much as you want.
Q2: For your info, on PO Deoxys-A can learn Iron defense, Deoxys-D can learn Zap cannon. So, yes, you can keep the moveset between forme change.
Yes you can change the form many times and for the second question I'm gonna say no seen as it learns no moves when it changes form -think about certain prevolution moves they can be learned by 1pokemon but when fully evolved and you haven't forgot it you have a move you can't learn ;)
