I used Thanos and CA Maelstrom in a 600 point Tourn. With 60 in feats (unnecessary I know). This turned out to be the best possible strategy. People were so focused on Maelstrom they didn't notice Thanos (with Shellhead, Vendetra, monster hunter and repulsor shield) was blasting away at them every single turn for 5 damage (had a perplexer hiding in the corner of the board). Thanos in two matches remauned UNTOUCHED. This includes the championship match. He destroyed all.
