Hey man great deck! Definitely a +1 from me.

I've always loved the idea of a good mill deck! It's one of my personal favorite ways to win. I'm not sure if you've done a lot of research or not yet, but I do want to let you know that Mill is generally considered as one of the weaker strategies in Magic. The sad thing is that it's true. That being the case, it has to be GREAT if you're going to play it.

I like the build. I think Persistent Petitioners are great BUT they're only good if that's one of the only creatures in your deck. You'd need 30+ in the deck for it to function well. You need at least 4 of them to even activate the ability. So if you go that route, you'd need to remove almost all of your creatures and replace them with Petitioners.

I think that can be very strong. However if you don't want to change the deck up that much, I still have some recommendations.

First things first, more ramp and card draw. These 2 components are the most important part of Magic. They are the foundation of your deck. Without them, it won't perform as well as you'd like and as quickly as you'd like. I run at least 10 forms of card draw and ramp each in my decks. AT LEAST 10 each. I know that seems crazy because that's 20+ card slots taken up but it's so necessary.

A great card to consider is Intruder Alarm . You'll be able to tap your creatures, mill your opponents, untap them when you cast a creature and mill them again, then untap and mill again every time they cast a creature.

Another good one is Mesmeric Orb . It will end the game quickly. You're milling yourself as well with it BUT you're making your opponents mill more than you with all of your other synergies so the game should end in your favor.

I'd remove the Jesters Cap. It's not doing anything great for you. There's so many good cards for 6 Mana that you could use in it's place.

I hope this helps. If you'd like more specific card draw and ramp options, let me know.

exalted_k1d | Before I start, fine suggestions all round! Thank you! | Show and Tell , Academy Rector and Omniscience . | Now these are some spicy cards and the Rector into Omni is a spicy combo, Show Tell is a little questionable due to the advantage you're giving to your opponents however. If anything, I'd want Rector in just for the immediate value if he gets removed, Omniscience is sort of a dead draw in a late game situation where I'm looking for a combo piece.

If anything, I'd be putting Rector in, now how do I remove him...?

| Sensei's Divining Top and Sylvan Library . Actually these pieces and Scroll Rack would all be good for the deck in their various ways, I simply haven't picked them up yet! Those price points are a big factor when it comes to me affording other things like my rent, or food, or general living.

Sensei's Top specifically is a little underpowered to contest with the amount of card draw in the deck, so I'll be passing over it.

| Countermagic. Just a personal gripe? Not too into it all. I play a 1 of Counterspell until I can get my hands on a Mana Drain or a Force of Will and that's it. I even took out my Dovin's Veto for some more tutoring, I just don't like control playing at all. I know this severely 'depowers' my gameplan with far less disruption interaction, but in my current meta, not much is actually being played either - helpfully!

Thank you for the suggestions!

Metachemist | My opinions on Chulane, Teller of Tales is that he's drew back by his need for the spell to be cast and not simply cheated into play to get a draw. This turns off some of the flicker effects with Brago, King Eternal , but synergises well with the many bounce effects from things such as Jeskai Barricade and Shrieking Drake . I would probably also have to change up many of my creatures from defenders to other things, due to the fact that without Arcades, the Strategist they have little to no viable combat potential outside of having out specific 'defenders attack' cards, which makes some of my very unique mana creatures such as Axebane Guardian and Overgrown Battlement left with no viable replacement.

He can however facilitate a Bouncegine (Bounce engine) with Intruder Alarm out, so it's a good thought!

Roon of the Hidden Realm seems cool! A little expensive and outclassed by other cards at this point but he has his place. His effect can't really be helpfully combo'd as you can only do it on the same creature once per turn, however.

| Alternate Win Cons. I was actually thinking about Blue Sun's Zenith as a trade in for Pull from Tomorrow . Although it costs 1 CMC more, it can target opponents. After you clear out your library into your hand it'll also be the only card you draw, so after setting up a Flengine (Flicker Engine) or Bouncegine you can draw the card after shuffling it back and cast it again for 6000 on your next opponent. Still questioning this however.

Finale of Devastation seems utterly devastating and I'd probably be running it if I had it. Big stompy crater boy would only seal the deal but he seems a little out of place? I'd just Finale for X=14000 and swing in for massive hits. The trample trick however is helpful.

On the topic of Lab Man and Jace, they just seem a little overplayed. if I draw out my entire library I should be winning regardless - might as well do it in a flashy 'royal flush' way as opposed to a trashy 'ace-high' way.

Again, fantastic comments and helpful insight, will be amping up the Maybeboard shortly. Thank you!

This deck seems to generate value off Jeskai Ascendancy and Intruder Alarm . I think the 2 CMC mana rocks could be cut for more utility creatures.

Eternal Witness is always solid but especially alongside effects like Temur Sabertooth

Heartwarming Redemption not a true wheel but still good.

Your list looks good. I think you could cut 2-3 lands, since you run a lot of mana dorks. Maybe Drift of Phantasms is a good include. It can search for Intruder Alarm or Cloudstone Curio .

Hello, KayneMarco! I wanted to drop you a line and get some advice. I was inspired by your Sliver Deck with no Slivers, and would love to try do something similar, but instead with Sliver Queen . I've got a copy of her, and would love to build something that isn't sliver-based and sliver-cheesy. I think her ability could play into some combos, though, and want to build around that. For instance, a sliver token in play, Ashnod's Altar , and something like Blood Artist is an infinite combo win. Some mana dorks and Intruder Alarm would produce infinite sliver tokens. Things like this. I just wanted to bounce the idea off someone and see what they thought.

Thanks for your time!

Another SUPER FUN card I forgot to mention is Cryptic Gateway . It combos really well with Intruder Alarm .

Tap 2 zombies, put one into play, untap all of them and do it again!

Pair this combo with Kindred Discovery and you'll be drawing and casting zombies like crazy!

Pair these with your commanders Scry/Drain ability and you'll be able to make a really big impact on the board.

These suggestions are more for fun and an interesting idea. The previous comment is much more important.

XetZero | On the topic of Iso and Dram, I have found that boardstate once or twice, but I usually have some sort of target to hit with the infinite mana, either with tutor magic or otherwise. Arcades isn't Thrasios, Triton Hero unfortunately, but it often works as intended.

I run Armageddon as a bit of a running gag in my meta, but I also find it to be quite the defensive piece, knocking out all those lands gives me some good time to prepare without danger and all the dorks in the deck allow me to have a good advantage over people when all the lands are gone.

I was thinking about Freed from the Real and I actually wanted to get one in the deck, never picked one up though. The combo is cool!

Chulane is a little on the high CMC side, which I'm not actually scared of playing at this point, but again, I haven't picked one up, also the fact that the cantrip is only on cast is quite iffy. However, the bounce from Chulane could be good for Intruder Alarm turns where I can untap everything.

Good suggestions all round, thank you!
