I'm assuming by the fact its called Create-a-Team 1 that, if this is a success and goes smoothly, the PokeCentre will run another one? Also, if anyone wants to see it, my two nomination reasons:
Pokemon: Snorlax
Tier: Overused
Reasoning: Snorlax doesn't get nearly enough love anymore, especially with alot of its counters dwindling in use. Its a great special sponge, letting it come in on baited ice or fire attacks with easy, and once its got a Curse or two up, the number of physical Pokemon that can hurt him drops severly, most of them are on the bottom end of OU, as well. Thus, with some good support, it becomes easy enough for Snorlax to sweep a team.
Pokemon: Heracross
Tier: Overused
Reasoning: Most people assume that with Scizor getting a priority move, its now infinitely better than Heracross. However, a late-game SD Heracross is rather hard to take down, especially with Guts making WoW mostly useless and TWave not as useful. Megahorn and Close Combat make for some absurdly powerful STAB moves, with the possibility of Reversal instead of Close Combat, as was the standard during RSE. Lastly, Stone Edge allows for some great coverage with Megahorn and CC/Reversal, letting Heracross also be a great late-game sweeper.
