Dance Floor Queen - 10 APDazzler dances across the battlefield on disco skates, landing amped-up blows and high notes with ease. Dazzler creates 3 Strike tiles with a strength of 72. For every 3 additional Red AP she has when this power is fired, create 1 Strike tiles with a strength of 72.
I like the idea of Gamora to capitalize on the passive stun, as a third I'd say Medusa to keep the blue & green flowing. The downside is unless you're just starting the 4* transition Gamora will probably tank red & black. Thorkoye is also a pretty obvious pairing for her green, but her black & red would be useless.IM40 & Nico could be fun. No active black & they overlap on yellow, but Dazzler should tank her colors & have red to spit out strikes or green to AoE. Nico will help with special tiles, too, and potentially remove CDs & another stun. Otherwise I can't remember the last time I saved up 30 red to make the most of her power.
I've been having fun using Dazzler in Hearts of Darkness, pairing her with Okoye/Medusa. Dazzler's (relatively) cheap green (7AP) has been especially effective at clearing out entire teams of foes with a few team-up APs in the bank.
I had awesome fun in the loaner node when you had to play Dazzler and Mohawk Storm together. Throw down a Hailstorm, then follow it up with Sounds of Light and Fury for massive team damage. That node is usually a bit of a drag, it was fun to play characters with awesome synergy for once!
(though it helps that my Dazzler has 5 green covers already...)
