slash---great build. you've come a long way with this deck. also, welcome to team ivy
i look forward to seeing this thing at states.
I'm thinking, how about doing 3 copycat and 3 steven's advice since your only straight draw method is the stevens?
also, definitely run 4 boost. do you really need to worry about wasting an energy attachment when you've got all the time in the world on the bench??
lastly, i'd think about running even 5 counter-stadiums. if you ever get stuck with all your stumps gone and a desert ruins sittin in play, you're gonna have problems. I know alot of anti ex decks like queendom relies heavily on the 4 desert ruins. if you stump first (which i'm guesssing you are because it eats their strategy), that puts you behind a stadium.. What do you think??? the only reason i'd consider something like this is because all of your matches are going to be incredibly long.
also, you're going to have to worry alot about the gengar curse. its gonna hit your bench and atm rock your poor little pidgeots and politoed...
finally: if you punch and run their gengar LM for a fossil does the curse powder hit your politoed or your fossil?? i'm guessing politoed??
--Ludicolous
P.S you might even consider finding room for warp point if they're building something tough on the bench and you can't afford to discard another fossil.
