Wulfsbane ain't all bad for all out attack but you can't do his throws (AKA like you know, almost all his worth lmfao) but you can just do a basic combo then sweep or use geatish trepak. The units that rely on crits like Parasite Weave or say No Egrets are flat out harder to use because of their crits lingering on all moves. You're better off boosting your defense on your units and then get hit by a BB3 which most likely give you a status anyway, and then reap the perma regen and enrage like I do with my Wulfsbane (Let me tell you Tuba Tuba Tuba finally gets it's just deserts!) or use a character that simply buffs themselves instead (Robocopy, Pyramid Scheme)
That said, don't forget to not use any abilities past level 3 to stop them from using their inherent effects! (I.E Ringlet Spike at level 3 on hit gives bleed).
Rack up that defense and let the opponent give you the perma r/e!
