Standard Black-White angels deck (I don't claim this idea, I first saw it from Hoogland). Resplendent Angel, Seraph of the Scales, and Lyra Dawnbringer are the core of your strat. Then I also have 2 Shalai, Voice of Plenty as she can eat some decks alive and is still vaguely annoying in the event she doesn't win tremendous value.

Tithe Taker messes up counter spells and is 2 blockers vs. aggro while Adanto Vanguard can sometimes ran away with a game all on it's own vs. control decks that don't mainboard Moment of Craving and in any event you are glad to see it eat exile removal. Currently trying 4 Seekers' Squire for the consistency granted by the explore trigger, and honestly having to pass priority on mtga constantly with adanto is frustrating, especially against combo/control decks.

Currently running a large removal suite of Mortifys, Consecrate // Consumes, Vraska's Contempts, and some Cry of the Carnariums. These are to be fine tuned as the meta settles and to be taken out/replaced/tuned in the side board. Note that Consecrate // Consume is an incredible card, as it is amazing vs. Carnage Tyrant, almost always eats the most threatening thing on the board, isn't too bad vs. aggro decks as even if it only kills a 3/X it is worth the life gain (and is equivalent to contempt when eating a 2/X), and in the event you face off against those dreaded creatureless control decks you can cycle it (and usually pretty quickly as it can eat cantrips and Chemister's Insights from their graveyard!) Furthermore, the ability to exhile The Eldest Reborn targets (namely teferi) as well as Arclight Phoenix/Rekindling Phoenix from the graveyard is also a worthwhile ability!

Memorial to Folly helps to pad threat density and give us something to do with extra mana/dead cards in hand.

As with any midrange deck, the biggest inconsistentency is sometimes you can draw the wrong half the deck. Somtimes you draw Adanto Vanguard into an intensive course on the History of Benalia vs. control and beat them to death... other times you draw a hand of removal you can't use and just watch them durdle and draw cards till kingdom come. Generally vs. aggro if we draw Lyra Dawnbringer or Shalai, Voice of Plenty and some incidental life gain via Consecrate // Consume/Vraska's Contempt we're fine, but otherwise we can get burned out. The sideboard helps by letting you replace removal with hand hate vs. control and less efficient removal with the excellent but possibly risky-to-maindeck Moment of Craving vs. aggro.

Maybeboard shows possible inclusions and their probable number, either in the maindeck or sideboard. Tocatli Honor Guard beats up on explore decks real hard and doesn't bother us if we board out Seekers' Squire, Orzhov Enforcer might be great for a slower more controlly variant, Plaguecrafter efficiently eats no-creature teferis, while Profane Procession // Tomb of the Dusk Rose/The Eldest Reborn could make a more grindy variant, and lastly if Hadana's Climb // Winged Temple of Orazca/Hydroid Krasis counters-matter decks become a thing Suncleanser might be an interesting two drop, as it blocks like a champ and eats counters (while outright killing a krasis).
