I hurts the green is taking a beating, but I must concur it lacks creature removal and game breakers which leaves it coming up short against crazy stuff like mana vapors coupled w/ rhystic lighting & withdrawls. But green has done well for me as my creature color with spitting spider(what a great threat!)spore frog and Darba. I used green/ black in a BD at the Orlando prerelease very effectivly, beat a very putout judge in no time flat - boy that was fun
And again I concur blue is very strong in PY with fliers left and right, semi-broken withdrawl, mana vapors(can give that one turn edge you need),overburden (screw you red/green!) etc.
Red is a gross damage dealer in PY BD, it is chock full of very good creatures, Fault Riders is all I'm sayin'. But its strenth is its weakness, in the last draft I was in , I played Blue/Green (give it up to the six spore frogs), I was the only one out of ten who did not attempt to draft red! Not enough to go around. My buudy won w/ Blue/Red but he couldn't play as much red as he would hve liked. So I'm done, keep it up ya'll.
