Nice format! I haven't the time for a huge detailed responses, but I did notice the allowing of LTC. This is not a good idea as the matches will already be about an hour or two long because it's 4 players, and adding in LTC will only make it really long, maybe even to that point of a D&D game! 0:
Also Honchrkow is overpowered.
Could you explain the banning of Virbank, Garbotoxin, and the errata of Brigette? Colress I can get seeing as how you can get up to 32 cards, but I'm not really sure of those. I know they all have increased viability, but does that really mean a ban/errata?
