From play experience, the antisynergy with artifact ramp and planar cleansings really wasn't that bad. The deck has fairly light draw, so we're usually only playing 1-2 spells a turn anyway. The ramp is there to get Athreos out ASAP, and it does that job admirably. After that, if it sticks around, swell. Also, only 1/3 of our wipes necessarily hit artifacts, so they don't necessarily even die.
Reclamation I'm lukewarm on because it doesn't really have much else to hit besides lands. It's basically a
Deep Reconnaissance with a double-powered flashback, which is not that exciting imo.
Brought Back, though, I do think I like, we should be able to hit double fetches into a sick double ramp turn reasonably often. And more importantly, it's actually pretty useful late-game to recur some value creatures. I'll probably throw it in for tomorrow's sesh.
Second sunrise I don't think makes sense, it's 3 mana and I don't think there's many circumstances where I'll get enough value out of it. And it's not really usable the same turn as a wipe.
I've already got the 9 good fetches in the deck. I'm not so sure about the etbt fetches, seems a bit jank for only one synergy card. Same for lotus vale I think, although that might have more merit.
Lake of the dead...Idk I really don't like that card. You have to sac 2 swamps before you get any value of it. I do want to ramp out Athreos but I don't think I'm in THAT much of a hurry.
Kor cartographer might actually be a good call since it ramps directly to 6. Crap solemn is still ok. Also might justify going in on
Emeria, the Sky Ruin.
Gids and Sorin are mostly a way to progress if my opponents aren't committing to the board, and they dodge most of my removal (Gideon dodges I think all of it actually, except an o-stone/boompile activation on an enemy turn). Or I can just get emblems pre-wipe. Admittedly P/T boosts aren't super powerful here, but the deck doesn't have the fastest clock for actually closing out the game once I've established control, and they speed it up a bit. Elspeth doesn't play as well with my wipes since she won't leave anything useful behind unless I get all the way to ult.
I considered the Ereboses but, at least from initial play, draw wasn't really that necessary, the deck has a lot of high impact cards and paying 4 for a do-mostly-nothing is eh. Having a sac outlet is mostly unnecessary as we have a lot of those in the lands. Of the two, bleak-hearted is definitely much better though, I could see running that. He got cut fairly late.
Karmic guide was cut because you cannot put a coin counter on it (easily).
Arrogance is way more powerful an effect than Gearhulk, and repeated locks aren't generally the goal. I do ultimately have to commit to the board to win. In my experience when enemies get to select what they sac, it's not that powerful of an effect anyway, tbh, more useful for making me a target than for actually clearing the things that matter.
Mistveil plains seems unnecessary? Not sure what that'd do for the deck. I have as much recursion as I have tutors.
