Tameshi, Reality Architect EDH (EDH / Commander)

Combos to be aware of:

1. Grim Monolith or Basalt Monolith + Power Artifact (infinite mana)
2. Isochron Scepter + Dramatic Reversal + 3 mana worth of rocks (infinite mana)
3. Seat of the Synod or Ancient Den or Treasure Vault + Copy Artifact + Lotus Bloom (infinite mana)
4. Basalt Monolith + Mesmeric Orb (infinite self-mill)
5. Sensei's Divining Top + The Reality Chip + Etherium Sculptor (infinite draw)

Additional Notes:

WTF Jack-o'-Lantern?! Lets you go off after milling yourself with basalt monolith in that it lets you turn basalt monolith mana into white to get back your lotus bloom. Make sure you leave a card behind in your library to draw with Tameshi, Reality Architect!

Portable Hole is very searchable, it is in the deck almost specifically to out cursed totem, collector ouphe, and null rod.

Predict could easily be winds of rebuke. You will know your top card a reasonable percentage of the time and it gives you an additional way to interact with top deck tutors and doomsday, but rebuke gives you extra interaction instead of the card draw and has synergy with your commander. Enlightened tutor for lotus bloom into either entomb's your lotus petal.

Similarly, Artificer's Intuition is handy for tutoring lotus bloom to your graveyard by activating it twice.

I'd play a lion's eye diamond if I owned one. I'd probably cut isochron scepter and dramatic reversal.

You can muddle the mixture transmute under standstill

Moonsnare Prototype is fairly average in play, but importantly it can be used as removal under standstill and searched with artificer's Intuition to pitch to a force of will or force of negation

Both goblin cannon and walking ballista are played as redundancy. Goblin cannon can be brought into play with Tameshi, Reality Architect where walking ballista can be searched with artificer's Intuition. As an alternative to goblin cannon you could play codex shredder.

Treasure Vault is preferred to darksteel citadel for the scenario where you have infinite colorless mana and need to turn that into infinite colored mana. Playing both is reasonable but the deck has a large colored mana requirement.

The Reality Chip lets you tap mox amber for mana too.
