Hi,
Both Nullify and Reverse magic have red reveal cost, which I have interpenetrated as mandatory to flip over if it is triggered. But what if you have both of them attached to one creature at the same time?
Lets say you do and your opponent cast a Sleep. Can you then choose to only reveal Reverse magic and keep Nullify? Or do you have to reveal both? Will you be able to perform Reverse magic then even if it is Nullifyed?
