User blog comment:RedDogSlay/Substitute Instead of Duel-SGX/@comment-24584996-20140915034207

If this was on the japanese version, I would happily make Duel-GX as leader for you (Haven't evolved to 6 star yet as I have no Zebra or Maxwell leader) But sad that this is the global version :( Anyway, yeah I've seen many substitute that would be okay to replace Duel-SGX and I also saw that you don't have any of the other crit units. For your Rashil, I don't know if it's such a good idea to bring him. I can see as substituting for Duel-SGX, but it's his class that makes me worried. A Breaker Rashil would be hard to keep alive unless you had a way to keep on doing his SBB which allows Rashil to survive any attack that would normally kill him. All in all, if you were going to summon Duel-SGX, do it when an rate up event kicks in, then go summon and hope for the best :)
