This is a guide to 2 double caster team compositions with very different and yet very rewarding playstyles.

Team 1:
This team has insanely strong teamfight capabilities as the synergy between the four aoe ultimates and the corki's aoe dps will shred teamfights in mere seconds if the amumu pulls off a good initiation.

Pros:
Massive teamfight potential
Decent sustain due to double Will of the Ancients
Quite a tanky team
High Burst damage
Decent poke damage with rockets and vlad/kennen Q's

Cons:
Mostly magic damage so magic resist stack may leave damage lack luster before void staffs
If initiation fails this team is weak until the ultimates cooldown
quite low mobility team


Team 2:
This team has incredible poke damage which should be used to their advantage by forcing long range trades while using gragas ultimate to counter any attempt at an initiation by the enemy team. This team will just poke with high range spells, heal any received harassment and pressure the enemies under turrets

Pros:
Incredible poke damage can overwhelm enemies under own turrets forcing them to give up turrets without a fight
Good healing capabilities to keep a push going from soraka and nidalee
High burst damage

Cons:
Requires a decent success rate on skillshots
Mana intensive to keep the poke going especially for nidalee
Aside from maokai quite a squishy team
If this team gets hard engaged it will likely lose the fight unless maokai or caitlin is fed
