Esme the Dancer (feb fusion champ)
Looks quite good. On the surface it would seem to be similar to Razel, but I think the better comparison is against Ukko. You lose the ATK down and ACC down debuffs, but you gain a much more reliable buff removal, along with an ACC up and an AoE ATK up on an A1 (!!)
The passive is just whatever, but the active version of the passive is *really* strong. If you make her fast enough, she's going to enable setting your nuker champ with basically zero speed, and just rely on her to boost that champ to get turns.
In fact, I think she will replace both Ukko and Arbiter on my team, which opens up a whole bunch of possibilities for the remaining spot.
