I have! Actually covered it last month: https://quietspeculation.com/jan-20-brew-report-amberning-up/

I started with that thought, but after reading both cards, I wasn’t so sure it worked that way. But I guess if Snapcaster works with Delve… that’s pretty sick!

I love that too! Interesting also that Moon is being so played despite many decks having a) snow basics to fetch and b) Astrolabes of their own. It’s no longer used to hose greedy-mana “balance” decks, as those are the ones that now pack Moon as a plan; rather, it’s for the combo decks that can’t run Moon because they lack the economy for Astrolabe or need their lands to go off.

In fairness, Modern’s never had the best color discipline enforcement in it’s lifetime. I remember Grixis Control trying to make Cryptic Command, Liliana of the Veil, and Anger of the Gods live together happily, never mind the shenanigan’s that went down while Deathrite Shaman was legal.
I think that Blood Moon is generally underplayed because a lot of manabases were already exceptionally greedy. It’s just taken until recently for the scope of that greed to become evident.
