Yeah. chesnaught will be a bit like Emboar, but with a worse movepool (no coverage really). Grass STAB + Fighting STAB + Rock move with Bulk Up/Spiky Shield/Belly Drum would be OK as an offensive thing. Delphox has a better movpool, but with a Pursuit weakness I doubt it'll go much further. Greninja has Spikes and apparently Rapid Spin, resists Ghost and can beat them with Dark STAB, but with bad defenses and not too good Special Attack, makes me think UU.
