Technically, if you want to sacrifice a Sash, Dunsparce has the potential to run a FEAR-like set, with Yawn/Protect/Endeavor/(attack, for example Ancientpower). Use yawn, then use protect if no switch (for one mon: use protect). The rest points itself out. This thing doesn't work in competitive due to obvious reasons, though. (Perhaps in AAA with Shadow tag/Arena trap...) I didn't use this in practice yet, but in theory it should work.
