A few changes to put through this time.

First, the swap to Teshar, Ancestor's Apostle from Mistmoon Griffin is an easy one, Teshar is both a cleric and a bird, which have themes in this cube and has added upside of some artifact synergy. I do want to put a little bit more importance on artifacts, so this card fits the bill perfectly. I may bring something back in that cares about graveyard order in the future, as I like that rule (you shouldn't be reordering your graveyard anyway!)

Withered Wretch was either a bear with tribal synergy or a complete hose against graveyard decks. Undead Gladiator fits in nicely instead as a potential turn two cycling option.

I'm cutting the two-card combo of Tireless Tribe and About Face to bring in a little bit more recursion for white in the form of Sevinne's Reclamation, and a haymaker for red decks with Fireblast. Mono-red is in a good spot at the moment, this shouldn't push it too much higher.

Fixing is getting a bit of a bump-up with the checkland set (e.g. Sulfur Falls), replacing the tapped pain land cycle (Caldera Lake)

Cloud Key or Helm of Awakening were the two potential options to go in, and I opted for the one that is slower for storm decks, just to keep them in check.

Forgotten Ancient fills a similar role to Hunting Moa and just looks like it will feel better in most decks.

Opalescence was a weird card, basically only being picked up by all-in enchantress decks. Noble Purpose is a bit more flexible in just giving all your creatures pseudo-lifelink, in a cube where lifegain is a rare effect. Enchantress should still be on the same power level as before.

Next update may be a bit of an artifact and fixing buff, I've got a few cards on my maybeboard to consider.
