Personally, I try to avoid EVO players too, Warehouse or otherwise. When I'm in the warehouse I always attempt to make sure we both get to play all of our cards to best effect, but I don't want to be limited to one style or another. I've had EVO players try to close out a match in round three after they leveled the one card they needed xp for using fury. Personally I could care less about who wins when I'm there to level my cards, but if your claiming a 'play fair' system, then, play fair.
That in mind, in tournament play, I play to win. I don't bring cards that need to level, and take EXTRA care to avoid EVO players. (Some people bury the letters in their name making it hard to see) Even then, some people are "Stealth EVO" players. I had someone chew me out for not playing EVO in Dark Corners West, during a tournament, when they didn't even have EVO in there name. Hey, I've come to tournament play forgetting to have swapped my deck out, and while I still play it through, I don't expect to win, nor do I attack my opponent for beating me. Oh well.
Good luck to you, Tupac EVO, I hope things work out for you. As for me, I think I'm going to focus on ELO
play from now on.
