Kurkesh, Onakke Artifact Shenanigans (EDH / Commander)

This deck is a little janky. It can technically win by milling all your opponents (assuming you last that long) but it does take roughly 13 wheel effects to mill someone out. Wheels can be copied or cast back from your graveyard to do as much.

The best way, however, to take it to the house with this deck is to dig for combo pieces and go infinite via infinite creatures or infinite mana into an X damage/targets burn spell.

Combos:
Kiki-Jiki + Zealous Conscripts
Twinflame + Dualcaster Mage -- target something random on your field with Twinflame, then cast Dualcaster. Copy Twinflame, then target Dualcaster with the copy. With the copy of Dualcaster, target the original Twinflame and repeat until you have infinite hasty Mages ready to annihilate your opponents
Mana Combos:
Voltaic Key + Gilded Lotus + Kurkesh = Tap Gilded for 3 red, use 1 red to untap with Key, then copy the untap effect with another 1 red via Kurkesh and target the key. Each round nets you 1 red mana. Repeat as necessary, then drop one of the massive X burn spells to win. If you don't have a burn spell, Myr Matrix can be used to make infinite Myr tokens with your mana. Bonus points of Myr Battlesphere is on the battlefield, because now one of your opponents will die as you attack with it and tap down an arbitrarily large number of Myr to deal damage

Prototype Portal imprinted on an artifact land (either Great Furnace or Darksteel Citadel) will allow you to pump out a copy of an artifact land every turn. Pair that with Caged Sun, Voltaic Key and Kurkesh, you could make infinite lands
