Both have very similar map pools, heavily favouring Bind and Fracture while staying away from Breeze and to a smaller extent Icebox. Tomorrow's match is gonna come down to individual performances.
For Optic Marved has looked like the best player on the team recently and after a slow starts Yay is looking a lot more like the top 10 player he's capable of being. One thing to note is Optic is very difficult to beat when Victor is playing well, he got off to slow starts in the first Guild series and his Kayo hasn't been that good recently. When Optic is playing at their best it's either him or Yay consistently getting first bloods and both attack and defence.
PRX has their two starts playing very well and Jingg is playing like the best raze player in the world. They are both being setup extremely well, double initiator comps look very well, d4v41 is having a lot of impact on Fade, forsaken running it down on neon following a prowler with a breach flash is scary to fight against. A key player for them has been mindfreak, he's had a lot of impact when put in the position of being solo site anchor, he's a smart player and knows when he needs to take space, play passive/aggressively etc.
