Vitamin D

Inspired by Sir Rhino's Deadliest Coach. I loved the core idea of the deck, so I've tried to really focus on being able to consistently play Yetipults and BSH's with deadly. I didn't find much success with playing Coach and then trying to draw into units, as it was too unreliable and Coach would get removed too easily. So I shifted to a recursion strategy, to ensure getting a deadly pinger by holding Coach until able to draw a unit from the void on the same turn. Almost certainly worse than a less narrow deck, but this is the kind of ridiculous combo jank that makes me actually enjoy playing constructed.

The idea is:
1)survive
2)loot a Yetipult (YP) and/or BSH into the void (bin yetipults first as they are preferable vs. aggro)
3)find a Coach and either a Dark Return or Last Chance
4)play Coach on either T4 (with LC) or T5 (DR), grabbing a Yetipult or BSH
5)if you can hold your recently acquired Rule-on-a-Stik and have a Hawk: go ahead and hawk 4 more of them into your deck. (this also mitigates the downside of Last Chance vs. DR)
6)wipe their board turn after turn

Matchup notes:

Against aggro, getting all the pieces together by T4/5 can be challenging, I'm still experimenting with different
options for the removal, and card draw & looting packages. If you're seeing aggro by T1/2, you want to focus on getting deadly Yetipults rather than BSH to ensure you don't lose by getting stuck with 5 power and BSH. You can also just hardcast Yetipult without deadly on T4 if you need to. Against token-based decks, Yetipult can be great even without deadly; especially on the play, as you can take out 3 tokens before they can play Xenan Obelisk or a T4 End of Hostilities.

The deck fares best against midrange and unit-reliant control. Kerendon Merchant gives us some legs against beefier midrange units, and Observer can also be a blocker if you've already got what you need in the void.

Aegis can be a pain, so prioritize trading Merchants & Observers for aegis units as well as trying to get them popped with Favor. Against Stand-based decks in the late game (7+ power), you can also use Hailstorm to clear aegis before playing one of your deadly pingers that you have a deck full of hawked copies of.

Scream decks are probably the worst matchup. I don't think the deck can really afford the space for more expensive or situational fast removal like Deathstrike or Rindra's Choice to combat screamed gold units without compromising the early game against aggro too much. If you can stabilize with a deck of DBSH, be sure to hold back one or two to block a berserk Rindra and the like.

Control matchups are where the deck really gets wacky. Recur hawks a few times (try and get them back in the void as often as possible unless you need chumpers), dump residual power with The End is Near once you're at 6+ power, and you can rather easily end up with a deck that is majority DBSH/DYP. And Yetipults even give you late game card draw to find even more of your sweepers.

Against unit-reliant control like Mask or anything using Azindel as a finisher, you can pretty easily turn into a prison deck by being able to ignore your side of the board while wiping them turn after turn. I had my most memorable ladder game thus far with this deck against Mask: I was drawing into DBSH's almost every turn, I traded BSHs for each of their 4 Tormentors, I wiped their 4 Azindels, they ran out of recursion, and at different points one of us each had 100+ health. The game ultimately ended with them conceding at 400+ power and myself at 12.

Relic weapons can be a problem, though it's reasonable to be able to have a high enough density of 4/5 strength BSH/YTP in the late game to just plop them out one at a time until they lose their SotSK.
