Sorry to be the only one asking questions, but when you say 4 numbers for us, 4 numbers for opponents, what does that precisely mean?
For example, MRAlyon posted:
2,10,15,24,25,27,28,29
Does that mean he can use 2,10,15,24 and I the last 4 numbers or we both can use creatures from that pool, plus creatures from 8 numbers I post?
