Help with my team please

Thank you for your help to all so far, it was very insightful, I have taken everything into consideration.

So I have jumbled some things around and made some changes so let's try this:

Swampert will hold Ice plate. (Powers up "Ice Punch") Ev's will change to 252 HP, 4 Def, 252 Speed
Scizor I'll give Adamant Nature and will hold Mega Stone
Togekiss will hold Leftovers 
Espeon gets Shell Bell
Lucario, How bout Timid nature and holding Expert Belt
As for Gengar. I'm swapping "Shadow Ball for Shadow Claw." I love the crit. Hit ratio and it just makes sense if SP Def is already lowered.

As for A Special Tank. How bout

Claydol: Ability - Levitate, Nature - Modest, Ev's - 4 HP, 252 SP Atk, 252 Speed
Stealth Rock, Earth Power, Shadow Ball, Ice Beam

Who should I swap out For Claydol? Espeon or Togekiss?

And I will be looking at either UU or OU
