On Floatzel, I would suggest replacing Ice Beam with Ice Fang due to higher Attack. Then, I would recommend replacing Surf (unless you still need it to navigate) with Brick Break. Disregard that if you still need it to navigate.
Jolteon needs a revamp. Jolteon has high Sp. Atk. Therefore, (she?) should have special moves. Specifically, I would recommend Thunderbolt, Thunder Wave, Shadow Ball, and Toxic or Light Screen. You definitely don't want to run all one type on one Pokemon.
On Emboar, replace Heat Crash with Stone Edge. This gives defense against the super-effective Flying-type.
On Zoroark, I would replace Fake Tears with Nasty Plot, so the advantage would continue against multiple opponents. Also (just what I would do), Shadow Ball over Night Slash due to high Sp. Atk.
On Togekiss, we again have a Special sweeper. I would say definitely cut out Extremespeed. Replace it with Flamethrower, SolarBeam, or Shadow Ball.
Finally, Garchomp. Everything's good here. The only possible suggestion would be replace Dragon Rush with Dragon Claw due to the fact that Dragon Claw is still strong, and has 100% accuracy.
