If you're going after raw mill, Perfected Mind is quite possibly the worst Jace out of the Mill ones. Memory Adept is far superior for destroying an opponent's deck, with the 0 ability being just mill 10 cards.

And yes, I get that Perfected Mind can be 15 cards for 4 mana, but at that point I've seen Tasha's Hideous Laughter deal more to a Modern deck for only 3!

I've run Infect in Modern, and 12 creatures is low enough already. As for Inkmoth, it is a land first. Trust me when I say with only 8, you're very, VERY unlikely to find them consistently without Mulligans.

Karumonix is an absolute blessing for any rat themed deck. Not only does giving all rats Toxic 1 really make players sweat bullets, but the ETB trigger is also amazing if you stock the deck full of rats.

Get it up to two counters, since just about all the creatures are 2's
Play them at instant speed at the end of the opponent's turn.

Could work!

This does look like a more Goyf'd up version of my deck Delirious Ramblings, and I think that there's a good middle ground between the two there.

I totally agree with Nethergoyf being in this deck, but it's Escape cost is essentially a Delirium ability, and without Artifacts like Mishra's Bauble, it can be a bit hard to proc. And yeah, I see the Capsule and Spellbomb, but that requires Urza's Saga to tick up 3 times to fetch one. That's more of a try it and see how it goes deal. (Also nice work seeing Enchantment Land as the card types!)
Cards like Stitcher's Supplier are great as well for trying to mill into that sort of ability quickly, but I do also prefer to have Grisly Salvage too as a one-off mill card since it also grabs a creature or a land most of the time. If you wanted Salvage, I'd say probably swap the Inquisiton to the sideboard for them.
It's also bit of a weird one, but if you have Delirium able to proc quickly and often enough, then Drag to the Roots is literally just a better Assassin's Trophy.

This is also a personal preference, but I'd have more Unearths in a deck like this since you have 17 legal targets, 8 of which are your key strategy and 7 help boost them very quickly. Since you have Capsule, Fatal Push and Assassin's Trophy/Drag to the Roots as removal, I'd probably swap out the Go For the Throat for another 2 Unearth and 2 Trophy/Roots.

I'd also work out a Sideboard since you don't have one if this is a competitive deck. I can always recommend cards to go in, but without knowing your local meta, it'll just be stabs in the dark.

Hope this helps!

I'd consider adding in Ichorclaw Myr since 8 creatures and Inkmoth Nexus is a very, VERY low creature count. Even for a deck like Infect.

Also works with Agatha's Soul Cauldron too! But unfortunately, that combo is a bit too hard to pull off in Modern consistently or quickly enough.

It is a lot of fun. They think that they have a solid line of play, then you just delete the key thing in their hand turn one and now they have to just start again.

Even more devastating after they mulligan once or twice, too!

Play Demonic Dread, and trigger its Cascade ability.
The card that Cascade finds resolves on the stack BEFORE the Cascade card.
Tibalt's Trickery counters Demonic Dread despite being cascaded for.
Resolve Tibalt's Trickery as normal, and hope you hit Emrakul off the effect that looks for non-land cards off the top of your deck.

I just find it better when the dumb strat actually works.

If you REALLY want to make this a viable option, going with as many Fetchlands to filter the deck out and avoid the possibility of all lands off Tibalt's Trickery might be an option.
Including the new Surveil lands from Karlov Manor!

A bunch of cards with CMC greater than 3 could also work, like Street Wraith, as there is already a (I believe it's called) Living Death archetype that already does the same thing in Sultai colours.

I'd scrap all of the following and replace them with Swamps. BASIC Swamps. To make the deck legal to play.
- Kindred Dominance
- Drainpipe Vermin
- Nezumi Bone-reader
- Locust Miser
- 10/12 Leechridden Swamp

I know that this is about discarding and lowering your opponent's hand size, but those things aren't going to work well together since after you make your opponent discard heaps, they likely aren't going to be able to draw.
I'd instead focus on getting out a horde of rats quickly and trying to overrun your opponent!
As others have stated too, 12 lands is abysmally low, even if the deck was all 1CMC cards. Not to mention that with your non-basics that enter tapped, you won't have the speed to actually do what your deck wants to.

Consider too swapping Relentless Rats for Rat Colony, as Colony doesn't rely on multiple copies of itself to get really powerful! AND it's cheaper to play at only 2CMC!

Similar thing on Moxfield. You add the card to your deck, then you can change it to a specific printing unless you search for that one in the first place.

So, uh, MH3 is finally out on here now.
That being said, with the speed that things are getting updated on here, switching to Moxfield still isn't off the cards.

There's talk on another deck here for a whole bunch of us to move to Moxfield. I don't like it as much as Vault for building decks easily, but they're actually keeping up to date.

I'm going to miss some of my old decks too, like the token deck that uses one of the most niche and detrimental cards for a token strategy to its advantage, or my Splinter Twin deck that was a Red/White burn deck with a Splinter Twin. combo in it.

Looking back over my old decks, I made some really stupid decks. Goat tokens, Mexican Tribal and Possibility Storm Emrakul all make me question what the me from 10ish years ago was thinking.

You can still do that unless the decks are "Unlisted". I have the same issue with my old account on here.

It is very interesting going back and looking at my older decks though, seeing how I used to think about deck creation and dying a little inside like when I look at my old paintjobs on some of my earlier Warhammer models.

Yeah, I know quite a few people who use Moxfield instead of here. Personally, I find this easier to use but I've always had issues with how long it takes to get new sets on here.

If that was the case, then the deck probably wouldn't have run away with so much of the pro-tour. "Dies to removal" doesn't exactly work against protection and counterspells being used back at you, and that is if you can draw them.

It's already been confirmed that the damned bird is more prominent and oppressive than Hogaak ever was.
Appeared in 25% of decks, including ANTI-NADU decks. It also has a [damn near] 60% win rate at the pro-tour, while Ruby Storm which people think will take over had a far lower win rate because the counters are easy to pull out.
