The safest bet is to rage of halone chirada, provoke and shield lob spiny at start followed by flash and circle of scorn. Depends on your DPS, MT will either provoke spiny off you first or you provoke Suparna off him first. There's really no need for melee to risk it with Wicked Wheel.
If you zoom out all the way, Suparna should still be on the bottom of your screen. I usually bait the slipstream first to go provoke safely since you got 20 seconds is over. Of course, I see it as soon as OT has 2 stacks so that's my cue for baiting. If you mess up the timing, just use a CD to eat it. Slipstream doesn't hurt that bad.
