For kicks during the Rangetrooper event, since you got to use a max Rangetrooper, I experimented with:
Ig88 lead, Gar Saxon, Range, Shore, and Magma or Snow or Storm. Range buffs the troopers, they counter, Gar assists like crazy (mod him for crit) and stacks an insane amount of Dots.
I know I took some screens where some of the enemies had 16 dots stacked on them. They would take a turn and just die. Was pretty fun.
In TW when we were really low GP I ran a similar team with 88, Gar, Visas, K2, SF since I dont have Range geared. It got 4 wins once and 2-3 other times. Now I would replace K2 and SF with Zaalbar and Mission. I dont think its viable really but was fun to run through GW.
Might be useful as a suprise team in GA. Counter and dots are good to keep the enemy from getting full points, even if they win first try because it pecks away at their protection.
