Apiary: Iber faction, when upgraded you can retrieve a worker each turn and gain farm income if you spend a resource. Super powerful. Maybe too strong.
Black Rose Wars: Chronomancer is RAD. Playing cards from hand is just awesome.
Terra Mystica: Witches. Flying around to forests and dropping dwellings is great
Circadians First Light: the lady who doesn’t need algae to send out her ships, I forget her name
Deep rock Galactic: Gunner. Unloading 4 ammo in one action to do up to 12 dice worth of damage is beastly, especially if Scout popped a flare for you
