Search yielded no results, so let's talk 5* Fac.

Re your team etc it's been said above mate so I'll just comment on SF. Yes, he's viable at 5* with gear maxed and proper mods. If he's your only dispelled though you'll need to speed him up. Hope this helps, he's a beast and will win you fights that you'd lose without him (especially if you can get 5's in your team as well)
