I suggest u set Life orb to blaziken and dread plate to Bisharp.
Blaziken moves: Flame blitz (blaze kick it's good too if u don't wanna suffer recoil) High jump kick knock off and protect/bulk up. I would run bulk up since i think protect it's no needed, but choose u.
Rhyerior cband ok, stone edge, earth quake, i would run ice punch over rock wreker and mega horn or poison jab
Exeggutor since runs Chlorophyll doesn't need trick room, or u set sunny day over trick room, or u replace jellicent with Ninetales. ( Sun it's a good support for Blaziken too and helps Rhyperior a bit since it halfs water moves power), and solar beam over leaf storm
Brick Break Bisharp it's ok, maybe Low kick it's better.
For Gardevoir maybe run the mega stone (u can find Gardevoirite in E18), and i would run: calm mind psichic/psyshock hyper voice focus blast (U can find that mt too in E18).
With those fixes ur team would totally change, since u would pass form a trick room to a sunny offensive team, imo it's better since a speed boost blaziken it's not quite good, while with a sun support it gets a serial killer. Also bisharp doesn't need trick room, sdance + suckerpunch it's veery dangerous and with lowkick/brick break u mainly hit steel mons which r usually slow. Twave in any case it's not recomanded for bisharp since it's an offensive mon and since if u still wanna use a trick room, half opponent speed allows him abuse of ur trickroom
