Need help with my team.

Azumarill - Huge Power/Jolly (Att/HP)
Tyrantrum - Strong Jaw/Adamant (Att/Def)
Honchkrow - Moxie/Adamant (Att/Spe)
Nidoking - Sheer Force/Timid (SpA/Spe)

I am also using (but here's where I need help)
Aegislash - Whatever/Impish (Att/Def)
Greninja - Protean/Naive (Spa/Spe)

I'm not have ANY fun with Aegislash or Greninja. They are super boring. Can anyone recommend something fun for my team? So far with my current setup I haven't lost yet, came close twice. Greninja does fuck all and goes down like a sack of shit and Aegislash is just really dull to use.
