The real trick is to also put Akiro's favor on Sosruko too. It's a lot of work, though, so it's probably more amusing than it is deadly.
Sure, AF would up the chance to taunt from 50% to 75% but may take a little too much work and mana ...
but consider casting Sosruko in strike range and then Rouse it ... that ups your chances from 0% to 50% and could be a real nasty surprise, then follow up a successful Taunt with a Jinx ... I figure If you manage to do that two turns in a row you may have gotten yourself a decisive edge.
And if you have another creature guarding for him you don't have to count on his defense holding up in melee either.
I'm looking forward to using this
