there isn't a specific combo, it's the usual play a ton of artifact mana, use PO to bounce them back and play them again while generating card advantage, eventually you hit a critical mass of cards and mana that your opponent can't compete with

the closest thing the deck has to a "big finish" is pic related, which often gets cast for X=1 or X=2 to break board stalls and take the monarch, you're rarely in a position where you need to rely on it to finish the game because lurrus already gives you so much value between mishra's bauble and thundertrap trainer

this interaction is correct but if you're casting PO with more than 3 targets it usually doesn't matter, you're going to win anyway
