I dont see why you have Pursuit trapper tomb as a Lead =/
Do you meant the Anti Lead Tomb?
Quiet
Shadow Ball / Shadow Sneak / Pursuit / Something?
Pretty stall weak at the moment, even Mixed Blaziken isnt getting past Milotic without hazard support.
And with Tomb in the lead position he'll be taking SOME damage, which leaves him open to be OHKOed by +2 Missy SB.
And you wont be able to invest alot of EV's into defenses if your using him as a lead position so that cuts down his ability to take on Ghosts.
