do I switch over to ROL hope before or after I upgrade some pillars to towers. I think I can get 6 ROL and have 4 SOGs avaiable
You can change if you wish
The RoL is neccesary for sure, and the SoG increase your winning percentage against alot of FG's.
Also, if you upgrade your fractal you can cast them earlier, which can make a difference sometimes, but thats not neccesary, neither are the pillars, you can start with those unupped and just work towards an upped RoL/Hope deck.
