There is a bug being exploited of cards with storm... I have captures, showing how the 2 cards with storm my opponent used chaining to infinity as far as I could tell. I say Exploit, because even if the storm effect is a 'free copy', IF there are prior spells to cause the number of copies! IF not, there's an exploit

first Grapeshot, then minds desire both chaining 15 times in the same turn, but we were not far into the match, and there WERE NO 15 prior spells to make the Grapeshot clone 15 times, then minds desire over that.
