Daze in response to Fatal Push on the stack to turn on Revolt.
I'm somewhat new to MTGO, but I have been playing paper for a while. I believe Revolt does not check until the actual resolution of Fatal Push.
I wanted to Fatal Push a mana value 4 creature by targeting it with Fatal Push, and in response, using Daze on my Fatal Push sending an Island back to my hand to turn on Revolt, and pay for Daze.
I've tried to do this twice, and it didn't work each time. It just came up as "Cast" each time, rather than the alternative, "Cast on a 4 CMC or less creature" or something to that tune. I can't figure it out, and I'm certain this is a "me" problem being a novice to MTGO.
Can someone explain to me how I can accomplish this on MTGO? Thank you very much.
