Hey all -
This is written in April 2021, after all the make easy updates. This is a little easier now but 99% of the people you face will be level20 with good level pins.
This is my team and strats I used to go from Bronze to gold..
Fahz, Grinder, Locust Drone, Onyx Guards, Kait, Savage Grenadier, Frag Grenade, Snub Soldiers.
The basic strat is to place either onyx guards or snub as first pin, in the center so they capture both covers either side. Use other pins to capture the first 2 sets of cover.
Fahz is useful to eliminate their big boy pins, then when they place a high value pin on one side, drop Grinder on the opposite side. Hopefully will take out a turret quick and give you time to get Fahz on to slow then.
Kait is useful to support Grinder if you need a little boost on his push.
Frags are great to deal with big clusters of them, or even a rogue Marcus slipping past your Fahz.
The Drone, Grenadier are mainly there as extra low value, cover getters, in case snubs or onyx dont appear first off.
Im no expert and I managed to wangle this one, so good luck all!!
