I've played another one for all... this time with Urgots...
that was probably the most op choice of them all. if one Urgot hits his E, everyone can follow up with up to 3(4 with 40% CDR) Qs which basically force enemies out of lanes. and in pre-teamfights you can easily kill one enemy with 15x Q.

Akalis syngergize pretty well too - you can use friendly W to hide too.
