And now we get to the tricky one. Monument to Perfection
Whether going through all those steps just to have a 9/9 with Toxic 9 is another question. Unlike Infect, Toxic only applies to combat damage, so Fling
Soulless Jailer
Soulless Jailer is probably not a card you're super excited about, but it certainly has plenty of applications in Commander. Prosper, Tome-Bound is among the most popular commanders, and Soulless Jailer prevents those players from Cascading through their deck for value. Likewise, it shuts off strategies that rely on Reanimate without affecting commanders like Chainer, Nightmare Adept. And while Soulless Jailer is a creature, and therefore relatively easy to get rid of, I think that could actually be an advantage. Dropping Rest in Peace against a graveyard deck is powerful, but can often take them out of the game entirely. Soulless Jailer is likely to have a similar impact without affecting an opponent's ability to develop their graveyard as they dig for creature removal. It will still buy you time to pull ahead without generating quite as much salt.
The Filigree Sylex
As far as board wipes go, The Filigree Sylex isn't the best one out there. It's also a pretty bad source of damage. But I've been reconsidering Ratchet Bomb-type effects, especially in my decks that don't make tokens. Both of these cards are excellent rattlesnakes, sitting in play threatening to wipe away any and all tokens in play. Especially if Treasures continue to be a popular way to ramp, these cards could be excellent escape buttons, forcing your opponents to lose their Treasures at awkward moments when they can't effectively use the mana. I wouldn't include this everywhere, but it could be something to consider if your local meta features a lot of tokens.
Mirrex
Speaking of tokens, the Mirrex is here to cause problems. A one-time Command Tower may be the best, but it will often be enough to get you out of mana screw. If you can bounce and re-play it, then this is basically a free Mana Confluence. If this stays cheap, it's something I'd consider for budget land bases.
Having the ability to create 1/1 tokens with Toxic 1 is something you won't use as often, but it is an interesting take on Inkmoth Nexus. It has powerful interactions with Doubling Season effects, potentially threatening to overrun the battlefield with Toxic 1/1s. Between Adrix and Nev, Twincasters, Doubling Season, and Parallel Lives, a single Mirrex activation nets you eight Phyrexian Mites. In a deck helmed by Sidar Kondo of Jamuraa, those tokens are also basically unblockable. Make Ludevic, Necro-Alchemist your other Partner, and you get access to all the token-doublers, haste, and a solid gameplan.
Even outside of dedicated token decks, lands that create creatures are worth considering. The Mirrex's mites are great Mutate targets for Snapdax, Apex of the Hunt. Having a reliable source of Toxic creatures that isn't susceptible to most removal will be valuable for any deck built around the mechanic.
The Mycosynth Gardens
The Mycosynth Gardens is the most outright powerful land in the set. Being able to copy any artifact you control is strong, and while artifact decks may not be able to recur lands easily, this lets your Mirran Safehouse also copy your other artifacts. Your ideal targets will have abilities that don't require them to tap, such as Welding Jar, Amulet of Vigor, and Esper Sentinel. This transformation doesn't wear off at end of turn, though, so copying Mana Crypt or Sol Ring is powerful as well. Copying certain Equipment, like Bloodforged Battle-Axe and Commander's Plate, is great for Partners like Akiri, Line-Slinger and Esior, Wardwing Familiar.
The Seedcore
Unlike Mirrex, I'd probably only consider The Seedcore in a deck built around the Toxic mechanic. Because Toxic doesn't care about the power of your creatures, unlike Infect, it won't be as impactful as Pendelhaven was in old Infect decks, but it will contribute more to your ability to deal regular damage, thanks to the mirrored buff. That being said, requiring your opponents to have three or more poison counters to activate that buff will likely relegate this card to dedicated poison decks.
Lux Artillery
When I look at Lux Artillery, I think about how much Arcbound Ravager messed up Modern, and now we also have access to The Ozolith and All Will Be One to make that deck even more lethal. Lux Artillery also works incredibly well in a Ramos, Dragon Engine deck, and we haven't even gotten to the second paragraph of text. Thirty counters sounds like a lot, but dedicated token decks can get there relatively quickly. And again, The Ozolith ensures that a board wipe won't get rid of the counters sitting on your creatures. Ten damage to each opponent every turn is a great backup plan for any go-wide token deck that struggles against Fogs, Ghostly Prisons, and equally large token armies.
Glistening Sphere
I wouldn't expect you to be able to tap Glistening Sphere for three mana very often. If you get someone up to three poison counters, you'd better finish the job quick because they're immediately gunning for you and only you. Glistening Sphere really interests me for its ability to Proliferate whenever it enters play. A deck built around Lux Artillery that can also loop Glistening Sphere a few times will get scary very quickly. Farid, Enterprising Salvager and Daretti, Scrap Savant both like Proliferating counters as well. It could even be useful in a planeswalker deck, ramping you early and putting counters on all your 'walkers later on.

Ichorplate Golem
Unlike previous sets from Mirrodin (Or New Phyrexia, whichever you prefer), we're not getting any cards that deal specifically with +1/+1 counters in All Will Be One. Instead, cards deal with oil counters, and as long as a card has one Ichorplate Golem provides a flat +1/+1 buff. If you're in need of a Phyrexian themed anthem, Ichorplate Golem works, but if you just want to boost your creatures you can do better elsewhere. Ichorplate Golem's power lies in increasing the amount of oil counters a creature starts with, useful for cards like Atraxa's Skitterfang or Archfiend of the Dross: anything that's only useful as long as it's oily.
Myr Kinsmith
With Urtet, Remnant of Memnarch coming in this set, I'm expecting an influx of new Myr-focused decks. Using Myr Kinsmith to search for Myr Galvanizer or Iron Myr will be a big part of success for those decks. In more generic artifact decks, this can still find Myr Retriever and Myr Battlesphere, ensuring that it's useful for Daretti, Scrap Savant or the new Farid, Enterprising Salvager.
Which brings us to the end of this artifacts and lands set review. There's a ton to be excited about here, from Sword of Forge and Frontier, which is good in any deck you put it in, to build-arounds, like Lux Artillery and Mirran Safehouse, down to niche support, in Myr Kinsmith. I'm personally looking forward to seeing what's possible with Mirran Safehouse and The Mycosynth Gardens.
What cards are you most excited for? Will they go into existing decks, or have any inspired you to build something new?
