We have some spare packs lying around. We were thinking of doing a 3 player pack wars. For 2 players, 30 card decks (16 lands, 14 spells) is usually enough that players don't lose from milling too often. In a 3 player match, will 30 cards be enough? thanks!
It seems like the worst thing that could happen is that you might need to add a second pack. But then, "hurray, opening MOAR packs!"
I'll do that. We had a play session on sunday but we didn't get around to pack wars.
