Umm... might I suggest modding your Rey faster? If she goes first you can either put lifeblood or the event special on a toon. (For what it is worth, I run Rey with a speed set and a health set at 531, I believe 503 is the speed to beat - Rey is my only 6 dot moddid character on the team, I also use JTR as my tank, g12 R2 for the smokescreen to avoid counters, and both heroes.
Gun straight for Kylo and deal with the adds once he is gone.)
(Also, do not use JTR turn meter reduction on Kylo!)
Hope that helps
