I've seen a lot of people discussing which units for each faction are good in matchups vs. other factions, and it led me to a question:
Are you allowed / do you like to customize your deck when you sit down across from a certain faction?
It may be that I just have a tournament mindset, but my first reaction is "No." For example, I have a PE deck built right now with lots of Warriors and Fire Beasts. If I sit down across from a CG opponent, I'm not going to take a bunch of commons out of the deck to put in Fencers and Guardians, just because they're better against the CG - my deck is my deck and I'll live or die with the consequences.
It does give me an idea for a tournament, though. This would seem to make the sideboard, MtG-style tournament attractive, where you play best 2 out of 3 games and can sideboard in cards after each game. So, I have to play my first game against the CG with my regular deck, but can then sideboard in some Fencers and Guardians if I see fit for game two.
How many of you do this now for your home games? Is it common practice to customize your deck depending on which faction you're up against?
