I definitely think EDG has the best comp.
-Viper is a needed pick for Pearl and Pearl should be played with 2 controllers just like Bind(and maybe Fracture).
-Fade is Must-Pick.
-Astra is the best controller for Pearl with Viper because the map is too big.
-KAY/O is the best flasher for this map without a doubt. It has long range flashes, a nade and a perfect ult to get in the site.
-Chamber is really useful in this map with his trap and for the B Long control. If a team wants to play duelist the duelist should be replaced with Chamber.
+Other Good Agents
-Neon: If a team doesn't want to play Viper or doesn't have a flex for Viper, Neon would fit Pearl pretty good.
-Jett: Replacement for Chamber and can play Operator.
-Sage: Her walls help so much with getting B control.
-Phoenix:Has great flashes for pushing A and mid plus defending A and Mid.
