Per Kevan’s comments on The Power Of vin Nestor, and Bucky’s own vote on No Combos; the Bucky/TDS pairing is fringe but not impossible.

Per me.

Actually, the Bucky/TDS combo makes sense given that Bucky has the third fragment they’d need to win.

That would also fit with Bucky proposing a game of tag where if Katastrophe and an accomplice were both carrying fragments, simply walking into the same room would cause the accomplice to automatically drop their fragments for the (now freed) Katastrophe player to collect and win with.

Ah, wait, no, it would be Katastrophe who dropped the fragments.
