Fixed Transformers Conversion (Megatron, Tyrant)

[gladiator1007]

Can anyone help me? I am playing Megatron, Tyrant in EDH and I am not sure how to convert him in my post combat main phase. Anyone know the action or steps?

Did you get a response on this? The trigger for megatron goes onto the stack, but you don't get a chance to click anything and he doesn't convert.
