I’m trying to champ everyone too, so I’m here for it, but at 1/1/1 it doesn’t seem worth playing him with a fortification strategy. Heimdall/Magik worked better than Heimdall/Shuri. I haven’t tried running any of the other 5* fortifiers yet; goblin, Hawkeye, Cable; unboosted in pick 2 I don’t think it’ll work. I may try Monica Rambeau since she is the only character I can think of who creates a fortified anything at turn start.
His blue (Odin Blessing) might be his best power. The board really fills up with those CDs once the parameters are met. And those strikes are big. Knull4* CM 5/5/3OdinOdin4* CM 5/5/3HeimdallOdin4* CM 5/5/3Magikjust a couple that intrigue me.
