Turtle meta in arena has settled in.  Four turtles, three in 2-turn SS, 1 not.  You weaken or kill one, Leo blows you up.  The other option is they dice you up before SS wears off because of how hard they hit if you stay away from the unprotected turtle.

This favors top players with oodles of SS and literally no one else, unless you have a god tier team that can handle SS AND lockout Leo's passive. 😓
