Cool idea; if I can be awake at 6am I'll be there!
A few things I'm noticing:
-Fractal and parallel universe should maybe be banned for the same reasons as nightmare/fate egg/mindgate, i.e. being able to get beggar creatures in a baron deck.
-I don't think immolation would really need a ban. Its main use is getting out big fire creatures quick, and if immolation is in your deck, you can only use small cost creatures. I suppose it could be used kind of like nova, though, to get quick quanta, though at the cost of 2 cards, but I don't think that would be a problem
-What is the reasoning behind banning nymph's tears/queen? I suppose you could give beggar opponents some nymphs if you really wanted to, but nobody's going to do that :p Was it simply considered OP for this environment?
-What about mutation stuff?
-Were both beggar and baron intended to have access to 4cc cards?
