My go to physical tank usually goes to this guy
Even though it can be a pain when I'm up against it, I still love it < 3
Another tank I love to go for when I'm look for special defense is assault vest tyranitar.
Ate up a lot of special attacks for me well, as long as the sandstorm was up ^^

Worked well with some physical sweepers I like using. If I see a dark type move going for this jelly, I just switch out to gallade or lucario with justified. Also with water absorb it can really be good with teams that aren't so great working against water types.
