Ultimate AG, Sig and R3 Rank Up

The_Doctor_24_1

Hello guys, I've been hoarding some items and with the last sale I was able to get even more, getting that saga AG, although I can't decide on who to use it. Most of this champs need high sig but I have enough to get them at least to sig150. I was waiting for the loyalty crystal to pull Void, but seems like it won't happen. Any advice or thoughts?
