Is Repurposing Bay a game-changer for Humility Shorikai?

Shorikai hasn't been seen too much in the meta lately, which is confusing, since it's able to deal with creature decks extremely effectively via cards like [[Humility]], [[Out of Time]], and [[Dress Down]].

The downside? Shorikai decks are, outside of going infinite with [[Dramatic Reversal]] and [[Isochron Scepter]], still reliant on creatures for most of their combos. Meaning that if they're going to go for infinite mana with Hullbreaker Horror, they first need to remove Humility.

But what if they didn't?

All Shorikai is trying to do is get to infinite untaps. Iso-Rev does a great job of that, but there is a flexible combo that makes a lot of things possible that also involves artifacts in [[Rings of Brighthearth]] & [[Basalt Monolith]].

As everyone knows, Basalt Rings makes infinite colorless mana. It is a little clunky in that you need to have the two mana available to activate Rings in addition to the three mana to cast Basalt Monolith, but otherwise, you got it. Now, that doesn't untap Shorikai, which is what we want, but it can do a couple other things with various cards that you'll find useful in the deck otherwise:

  • [[Voltaic Key]]: After you've made infinite mana, you can now infinitely copy the untap effect of Voltaic Key, untapping itself and Shorikai until you draw your entire deck.
  • [[Sensei's Divining Top]]: Same deal, only now you don't need Shorikai, and can simply use Top to draw your entire deck.

Now, we're now talking about two different 3-card combos, even if the two combos both have two cards in common. But what we also now have is the ability to go all-in on Humility, which is arguably the best creature answer in the format right now, with a meta full of almost entirely creatures and creature-based win-cons. That doesn't mean abandoning creatures entirely, but it does mean not having awkward seven-mana ones stuck in our hand that don't do anything. Because every single one of these win-con cards does something for Shorikai:

  1. Isochron Scepter: Put a counterspell on this, and you're going to have a good time.
  2. Dramatic Reversal: Does what it says on the card, likely paying for itself by untapping mana rocks to also draw more cards with Shorikai.
  3. Basalt Monolith: Seeing a lot of play these days even in decks that aren't going infinite with it, simply because it can be untapped with Keys, turns on Mopal, and is a bad ritual that gives you three extra mana the following turn.
  4. Rings of Brighthearth: Doubles draws with your commander if you have extra mana sitting around.
  5. Voltaic Key: Along with untapping Monoliths, it also untap Shorikai.
  6. Sensei's Divining Top: In a deck that can draw two cards on demand, getting to clear your backlog of Top cards you don't want makes it all the more useful in digging to find the cards that you do.

This gives the deck a ton of slots back, and still provides two different combo lines that get you to infinite untaps, not counting the real possibility of gumming things up bad enough that you can just token swarm everyone with 3-4 Shorikai activations a turn.

But back to the original point: All of these things are also searchable with new artifact Birthing Pod [[Repurposing Bay]], and several also synergize with it as well (Dramatic Reversal, Rings, Voltaic Key). While I'm otherwise pretty out on the Bay, this seems worth the effort to both include it in the deck and to build the deck a bit around abusing it (lets not go too crazy, we're talking about adding Corridor Monitor and maybe an extra Signet to the list and calling it a day).

So, what do you think, Shorikai or former Shorikai pilots? Is this worth trying out?

And more importantly, while I have you here, why isn't Shorikai doing well right now? As I said, it seems like Humility is the best card against the current meta, so what's been the holdup? Is it because of the clunkiness of trying to make it and Hullbreaker Horror lines work together, or is it something else entirely that I'm missing?
