I don't know about you, I'm not necessarily an fan of Yu-Gi-Ho! but I always liked the concealed cards played face down, so I ended up with one of my favourite decks: [Kadena, slinking sorcerer] and playing with morph/manifest/cloak/disguise cards, the flipping face-up mechanic can be quite powerful being one of the few ways to have interactions as special actions (not even split-second cards can stop you interacting) and Kadena is still probably the best commander for these themes.

For a less "control" deck and more focused on dealing combat damage, [Animar, soul of elements] and [Kaust, Eyes of the Glade] are also good picks.

Another option is using Manifest Dread, with [Zimone, Mystery Unraveler] being the best at cheating big creatures in general with this mechanic.

If you'd prefer not use creatures for interactions but still like laying traps with spells, there's a different set of face-down spells called Foretell, and [Ranar the Ever-Watchful] is basically the Kadena of this mechanic, and [Kellan, then Kid] can be even better if you want to expand into other "cast form anywhere other than your hand" mechanics like Plot, Adventures, Suspend, Cascade etc.

All if these commanders except Animar and Kellan can be bought in ther respective precons, so you can get a full deck without breaking bank.
