Just tried it for myself with Vassal, worked like a charm. Would have gotten an easy 7-8K if I didn't luck out and draw Summoner of Illusions on my last turn.
Out of curiosity, would Straight Flush work instead of Storm? He seems to really like filling up his backrow, and it's a bit less of a hassle to use.
Just tried it and the last 2 pinch hoppers I had were in the bottom 5 of the deck... so I didn't have one in hand and he tribute to the doomed the pinch hopper. It's risky to lower your life because he was holding the tribute for a while I think...
