actually i've sorta patched up the Heracross problem. Intimidate on Arcanine seems to be better although Chandelure is more of a threat now. But anyway I'll go for my current Arcanine + Flygon. Also I'll switch to Wild Charge now that bulky waters are sort a problem.
If Slaking gets another ability other than Truant(and Slow Start), it would be Uber with that monstrous stats.
