The combo has been improved again, and now we are at more than 2 -> 14 -> 231! All the recent improvements have been due to forum user plopfill.

The reason we are able to get more than one layer of recursion per card, is that the combo builds an "engine" of sorts that allows each additional card to add up to 8 layers of recursion. (or 11 in one case, but it's hard to do this more than once or twice)  So far we haven't been able to do better than a constant number of layers per card, but Russell  pointed out a combo that would turn X into X layers! Unfortunately, the cards could be used to go infinite, so it wasn't allowed, but it was a near miss. It is still possible there is a combo out there that allows us to go past omega in the FGH.
