Oh boy, lotta good stuff while I was asleep.
Forsaken Monument looks insane for brown decks. Guess it's hard to begrudge them an insane enabler given that they're playing with more restrictions than anyone else.
Akiri, Fearless Voyager I like more every time I look at her. I love that the ability is stronger in commander (for having multiple opponents to attack) without specifying commander on it. I love that boros finally got an equipment commander (I know
Tiana, Ship's Caretaker exists but (1) she's better with auras and (2) she's garbage). And I love that, unlike syr gwyn, she works with
Zirda, the Dawnwaker, plus protects him. Definitely one I'm likely to make soon, I just hope she flies under most peoples' radar so I can feel like a hipster. Is she weaker than Gywn? Probably, but syr gwyn is too easy mode, too much of a removal magnet. Akiri has way more nuance, absolutely preferable imo. I've been waiting for a boros equipment commander since 2013 and we finally got it!
Lithoform Engine looks pretty bonkers although the costs are high enough that it's probably not broken. If you're just looking for one ability, it's generally outclassed by other cards, but if you can get value from multiple - say a spellslinger deck playing fetchlands, not hard to do - then it's got a lot of value. I'm glad it taps, puts a bit of a limit on the power level and makes me hope it's a cool fun card and not a dumb broken
Paradox Engine card.
Skyclave Relic is very neat, although the breakpoints are pretty clunky for my
Kaervek the Merciless deck, so I'm not sure I have a use for it. I guess it's ok in
Zirilan of the Claw, but not the most exciting.
Inscription of Insight bleh, sorcery. It might have some interest for me as an instant but as a sorcery it's trash.
Maddening Cacophony Help, police, murder...
Ondu Inversion Phelddagrif getting the goods this set. I wish this had been the mythic so it'd come with the option to untap it, but this is the kind of split card that's perfect for the grif. Sometimes you need to wipe the board, and sometimes you just need to hit land drops to avoid capping out your hand. And of course you can always get this back to hand with a handy dandy karoo land late-game. Really really nice to have this sort of effect available at such a low opportunity cost, and I don't mind the high mana cost a lot of the time.
I give today's spoilers an A+.
EDIT: ooh, fun note - because of how akiri's ability is worded, she can give indestructible through
Lightning Greaves, plus won't kill a creature if it removes
Captain's Hook (although unfortunately other similar equipment, like
Grafted Exoskeleton, are sacrifice instead of destroy so they'll still kill the creature).
