My main thought behind us not seeing too many Final Fantasy 16 villains as Partner commanders is that we already have some other Partner commanders in the set that seem to be waiting for their own thematic pairings
1 Explorer's Scope
Cards like Bojuka Bog are immensely popular for this reason alone, and Dauthi Voidwalker is a perfect graveyard hate option with a bunch of extra abilities
For the rest of the turn, if more creatures enter, you still get to scry more, which is great
This deck gives up creatures for artifacts that function as elementals, which means targeted removal can risk you overcommitting to elementals, only to be left trashless at just the wrong moment (yes, having no trash is a bad thing)
But somewhere between Stronghold and Ravnica, we all collectively realized that the graveyard is actually just a second hand thats slightly harder to organize
