draft to sealed

i have not done a sealed toruny since the release of som and right now am half qworried about the ptq next week. i have done a shit load of drafts since then and i am hoping that the sealed format is no different than drafting, just having cards available to  you instead of actually picking them. the other thing that i am worrying about is getting a shit pool. i am comfortable with myself building a solid deck with a few tools, but what if i get nothing? i dont wanna be forcing  two golden urns and no myrs half a poison deck and a bomb metalcraft deck with nothing to finish with... i think i am a way better magic player that most people i know but the only problem i see there is that i live in the bay area. my store is lsvs store...and that store breeds competition and its very high caliber.but i supose thats not a bad thing...i just hope that sealed isnt much differet than drafting...i think i will write up a report for sixtycards....
