I hadn't considered a Cleric on my teams before as it usually slows down my offensive momentum. I understand that Chansey, Blissey and Sylveon seem to be the premier clerics these days, but are there any others that I could use in their place?
Vaporeon and Umbreon could also work:
-Vaporeon w/Leftovers
Nature: Bold
Ability: Water Absorb
EVs: 252 HP, 248 Defense, 8 Sp.Defense
Moves: Scald, Wish, Protect, Heal Bell/Toxic
-Umbreon w/Leftovers
Nature: Calm
Ability: Synchronize
EVs: 252 HP, 248 Sp.Defense, 8 Defense
Moves: Foul Play, Wish, Protect, Heal Bell/Toxic
I hadn't actually planned for a Trick Room team, but I've raised enough "slow" Pokemon that could easily function around a Trick Team.
My worry though is would Beeheyem be able to survive long enough to set up a Nasty Plot? I understand that it has just enough bulk to get a Trick Room going, but not am not overly sure about its chances of setting up.
That is a good point. Beeheyem doesn't appear to be the bulkiest Pokemon out there. You could use
Steel Wing Recover, Calm Mind, or another coverage move or something.
Would Bisharp be slow enough to take advantage of a Trick Room, considering he can always switch to priority attacks?
70 Speed isn't THAT fast, but you could run a set with no Speed EVs and a -Speed nature. Though a set with Speed isn't such a bad thing either, since Trick Room teams do need to have that one faster poke for when TR isn't active.....
