Dark Trooper w/ Snowtrooper combo

Has anyone tried this? Quite often, my dark trooper will go first in a fight. When he does I'm always tempted to just use pneumatic punch because of the damage but I was thinking. If you use his special which grants advantage to all trooper allies, and snowtrooper has come along for the ride (who gives 120% crit damage to all trooper allies) it seems like you may have a recipe for fun. I have seen quite a few people post about not sleeping on snowtrooper but I haven't geared/ leveled him much at all so I'm conflicted. Does he pair specifically with darktrooper better than say magma trooper who is entirely easier to farm?

Crit damage increase with mass advantage seems pretty tough, on the other hand magma passively and hugely increases tenacity.
