So far I've got the following cards on my Acquire/Test list:
In blue it's mostly just more support for the UW Blink archetype. Alirios has intrigued me since I first saw it as it's a lot of stats on a decent body and can get really out of hand with any blink shenanigans. It reminds me of that Commander card that made sculptures that couldn't do anything until it died.
Conjurer's Closet is too cute in anything aside from EDH, but Thassa comes down a turn earlier and allows you to curve right into it after a 3 drop (like Alirios) and can eventually turn into a beatstick all on her own to close out the game. She's splashy enough to be played in a Bant blink shell and I think she'll be pretty effective as an archetype signpost.
Intervention is just there to be a flexible counterspell/DTT hybrid, nice utility spell to reach a critical mass of effects.
For black the addition of enchantment creatures has made me want to revisit BG Constellation as a potential archetype. Aphemia is playable at its base as a 2/1 flier for 2, but will shine if it can generate 1-2 more bodies. I see it as a dual early threat + late game card as it can re-populate a decimated board if you have enchantments in the graveyard.
Woe Strider does a lot as a sac outlet and brings its goat buddy along to serve as fodder to block and smooth out your draws. I don't like extreme support for something like Aristocrats, but incidental cards like this are perfect since they're good roleplayers elsewhere. I'm interested in seeing how good Escape is in practice.
Nightmare Shepherd looks like another sweet piece for Aristocrat-styled decks, also just seems good in a generic grindy B/x shell full of creatures with ETB effects. The baseline 4/4 flier for 4 is playable on its own and the enchantment typing makes it even more attractive for incidental synergies with stuff like Delirium.
Eat to Extinction is just going to be swapped in for
Vraska's Contempt which was a wee bit too efficient for my liking with the lifegain. "Surveil" is a nice ability to have and will be randomly useful in things like a reanimator shell. The art is gross though. Yuck.
More stuff for potential Enchantress/Constellation decks! I really like the Champion as a creature that can curve into bigger enchantments. Much like
Beast Whisperer,
Eidolon of Blossoms always felt one mana too high up the curve to set up as an engine, but this slots in really nicely with current cards available. Being able to curve into
Nightmare Shepherd + something like
Doomwake Giant right after could be an absolute beating and grind you through slower matchups.
The introduction of Sagas in the last two years makes me really want to visit Delirium again as now we can more easily get an additional card type into the graveyard. Iroan Games slots well into a GB Delirium, Enchantress, and in my U/G Simic decks with the counter mode. This looks very powerful if you're able to fire off the 2nd and 3rd modes in sequence.
Uro is mostly a replacement for Oko who was a dumb fucking card to play with. The ETB effect is nice and I'm a fan of the reanimation not being so easy to pull off as other big dumb fatties. I don't know how easy it'll actually be to have this Escape in Simic colors, but using it early as a Growth Spiral and then being able to cash in on used up cards in the late game seems like a fine play pattern to me.
I really have high hopes for Shadowspear as far as equipment goes. It's cheap enough to deploy reasonably early, equip cost isn't too high, and it mimics the best parts of
Loxodon Hammer which was always way too slow for my environment. I can see this doing good work and staying in my cube for the long haul.
