I would say -1 Butterfly -2 Wardens +1 discord +2 animate weapons
...in my opinion you just need 2 powered wardens (one with big damage as main damage source and killer of the big ones and one with low damage to kill smaller creatures [so you still got one to guard airborne creatures and one for the butterfly]), the added discord and animates provide more damage, so you don't have to rely on your luck with the chaos powers
