I shouldn't be able to eat 12 Gigs of memory, even if I have 6 parallel lives type effects and use the Embalm on my Anointed Priest. Please find a way to make triggered abilities not take so much memory/time to load and unload to/from the stack. It took a couple minutes for the 4000+ triggers to even register for me. My opponent seemed to have another couple minute wait. I'd like to play exponential decks, but the system as written is incapable of handling them. Allow shortcutting if you notice it will take up memory - notice the same thing is occurring, then query how many times. You shouldn't need to create/destroy the object for each virtual card - put a multiplier on it, have a single object of that type in that general location (if you have two next to each other, group that pair and put a multiplier on the pair of virt cards, etc...). This will only take a single object's worth of memory with an int count instead of n objects - much much less memory, easy to understand, quick to load and unload.
