Tier List by Team BethelFrankel

Completely broken units; most are reliant on dupes. These units should never leave your main roster once you've built them.
Meta choices. Capable of handling 99% of the game; in fact, the high end S tier units here are capable of hitting the peaks that SS units have. However, they often require a little more support.
Off-meta units that can still be pretty potent in their own right. Many units in this tier still hold respectable niches or impressive damage; however, they firmly require team-building or luck to hit their maximum potential.
Units that can either be useful for newer players or players struggling to complete their teams. Still capable of holding their own when given support, but doesn't scale very well in harder fights.
Playable, but only barely. Units in this tier are not really capable of clearing the hardest content in the game, even with proper support. Play them only if you want to tinker around with janky effects, or have particular attachment to a certain unit while you do your dailies.
Bad beyond the early game.
