I just wanted some clarification on "play an enhancement abilities cannot be interrupted" in the REG. There was a thread about this a few months ago but I can't find it.
Scenario: Opponent has initiative and plays Dream (interrupt, draws, plays next enh). He then plays Two Thousand Horses (essentially repeating what he just did). He then plays Stormy Seas (PC) and completes SS's effect (discards two cards from my hand), and now I have initiative. I play Mercy of James and want to target Dream to get rid of his enhancements and cascade negate what he did.
What is the correct order of what happens now regarding the three enhancements (Dream, TTH, and SS)--what can be negated and what can't be, which cards remains in battle and which ones don't?
