Firstly, I apologize for posting in this thread, this is because I'm not allowed to post in the Judges Program.
Question is, can I target to interrupt a card twice?
For example: I play the ability, blistering fire. Opponent, in response, plays the ability, fizzle, to interrupt my blistering fire. In response, I play the ability, nether fissure, to interrupt his fizzle.
At this point of time, is it legal for the opponent to play a fizzle, targeting at my blistering fire instead?
The chain would be: Blistering Fire>Fizzle>Nether Fissure>Fizzle. In this case, Fizzle cannot be added onto the chain, as it would have to be in response to nether fissure. Thus, for the opponent to play fizzle, he would have to start another chain and interrupting the blistering fire. Is that legal?
