Need a bit of team help

I currently am using Magneto and Dante, but I have no idea what assists, nor what my other team member should be. Any one got any good suggestions?

Go… dante/ammy/mag

Dante builds his own meter and can kill,ammy is a great support and mags is an amazzing anchor

Dante jam session/ammy ice shot/mags beam
A good team that can switch between runaway/zone/rushdown and counters phx/wolve

Okay, so now I have been playing as Tron/Dorm/Task. Is that team really any good?
