So I just leafed through this last weekend, and I saw that the starting agreement looks like this:
(Round 1) Cast spell on self.
(Round 2) Ready counterspell.
(Round 3) Begin spell duel (I guess, anything goes at this point).
So, in the continuing discussion of "how useless is my counterspelling", I'm wondering what is the point of the round 2 mechanic? I guess A readies, B readies, then A attacks & B has a chance to counterspell? And then I guess the next turn goes to B because the ready action "occurs just before the action that triggers it", giving them an attack against a non-countering A, I guess?
