Well, it wasn't a duel. Just a discussion before classes began. There were a few things that we ended up agreeing on:

-You run Evilswarms as Evilswarms with no Steelswarm tech; it clutters the deck a bit.
-Rabbit engine is an option, but not mandatory.
-Triple Thunderbird guarantees a monster on the field for later use in Ophion or something. Really annoying, mainly because banish and back to field over and over and over again on basically anything.

's about all the time we had to agree on stuff about.
