It's still available in the Limited-Time SG Swap Shop too, but even though Versus Annihilation lasts until August, as it's now in a Prize List it might be removed earlier than that. Especially since they haven't removed the remaining Astral Guardians items from that exchange either.

So if you wanted to get it, grab it from the Swap Shop now because one SG Recycle Badge is cheaper than 2000 SG worth of scratches to get a choice ticket.
