Can someone help me out with my team? Not posting moves as I've got to go remember some with Heart Scales. Post any changes/movesets/items you think I should be using.

Tyruntrum - Adamant/Strong Jaw (EV trained Att/Def)
Aegislash - Impish/Stance Change (EV trained Att/Def)
Nidoking - Timid/Sheer Force (EV trained SpA/Speed)
Greninja - Naive/Protean (EV trained SpA/Speed)
Azumarill - Jolly/Huge Power (EV trained Att/HP)

I also swap out Butterfree - Quiet/Compound Eyes (EV trained SpA/SpD) and Pidgeot - Naive/Tangled Feet (EV trained Speed/Att)

I'm more than happy to dump Pidgeot/Butterfree. Butterfree has been wonderful, Pidgeot not so much. Who should I sub in for them? I feel weird about not having a flying type but if it's something else I'll just have to deal with it.

tl;dr help me with my team. Any help appreciated.
