I like my Magmatrooper paired with my Magnaguard100. My Magnaguard has an Omega shard for his standard attack, thus raising his damage considerably...which I plan to do very soon w/ my Magmatrooper. Anyway, my point is the two are gr8 as tanks especially when they get down to the very end of fights & have to trade licks w/ 1-2 opponents. Buuuut, my main draw is that they are a killer controller pair. Even w/ a slow poke leader like Lumi, they can add nearly a whole extra round of attacks in most opening rounds. Considering that Magnaguard is hitting possibly up to 3x in some rounds, (w/ Omega shards, he now does solid damage *2500* on par w/ most standard attacks) you can bring a lot of damage to teams before RG's/Chewies/etc get a chance to control. It's a weird off-the-beaten-path choice of characters, but it works.
