i would go for

dark seer
treant protector
ancient apparation
earthshaker
sand king



dark seer have to initiate battle by vacumming every opponent. Treant goes for the lock while the other 3 launches their ulti. But of coz, ur treant need to be the support type that is smart enuf to invi all of u before battle.

i doubt these heroes can be used for CM mode, es and dark seer usually gets banned.
