Thanks for all the answers above!

A thing or two more to add/ponder:

The whole 2-1-2-1 vs 2-1-1-1 thing is answered on page 11 in the "Two-Player Game" sidebar.

It says "... whichever player isn't triggering the battle plays 2 cards the FIRST TIME their turn to play monsters comes up."

Also, Giant, in regards to using IDKTCDT to target the Horde ability, I think the Ape gamer had said somewhere else in the FAQ or on this board that if you removed the horde ability after monsters were down, the players that played the last monsters would retrieve their cards from the battle stack until the size is appropriate. Is there a particular spirit or ruling to this question you think we should play by?

Thanks again.
