As explained in the event's page, he supers three times per turn in his 2nd PHY stage. Super STR should kill him pretty quickly, and you can always hope for SSJ3 Vegeta to either stun or at least tank, and SSJ4 Goku should also take the hit pretty well. Unfortunately your SSJ4 Goku and SSJ3 Goku GT are still undokkaned, but it shouldn't matter too much. And if you really want to seal him, you could use an item, in the end items are there to be used. But I don't think you'll need it.
