First of all, tokens can be shuffled into the library. It's just that when state-based actions are checked, the token will cease to exist as they cannot exist anywhere other than the battlefield.

111.7. A token that’s in a zone other than the battlefield ceases to exist. This is a state-based action; see rule 704. (Note that if a token changes zones, applicable triggered abilities will trigger before the token ceases to exist.)

Second, commanders can be shuffled into a library too. The reason commanders do not shuffle if they are moved to the command zone is due to the fact that the replacement effect (that allowed them to move to the command zone if they were to go to any zone other than the battlefield) replaces the event shuffling it into the library. If the player does not elect to use the replacement effect, commanders can be shuffled into a library.

Basically, as long as the card gets to the library to be shuffled, you will get shuffle triggers like Cosi's Trickster .

Hello planeswalkers,

If I use Chaos Warp , Oblation etc targeting something that will not be shuffled into the owner's library (for example a token or a Commander), the owner of that permanent will shuffle anyway?

Asking for effects that care about shuffling (like Cosi's Trickster ) and top manipulation ( Crystal Ball )

I appreciate all the thoughts guys.

Cosi's Trickster Thief of Sanity and Thada Adel, Acquisitor would be an interesting beatdown deck alongside Psychogenic Probe . It's definitely a telegraphed play, but either way you're still breaking parity and getting a tutor to topdeck for

I think that Scheming Symmetry and Psychic Surgery has a lot of potential. I found an older janky deck that ran Psychic Surgery with Extirpate and Surgical Extraction . A 1 cost anything tutor could certainly be an enabler for that deck, and it triggers Psychic Surgery

I also think Symmetry has some potential in combo decks. If you can draw the card and use it to combo off, you negate the opponent getting the card by flat out winning.

As far as the price, once people realize the large amount of cards that shuffle or mill an opponent, I bet this card will go up. It also has potential in other formats too, especially Commander. It has a few applications, its a 1 cmc tutor with a drawback that many effects can get around, and it can cause an opponent to shuffle.

Nice deck! I'd opt for Cosi's Trickster over Jace's Phantasm , but still a very nice list.

I'm not a huge fan of Mark of the Vampire when compared to other modern enchantments- most of the non-boggle auras are 1 drops that replace themselves ( Rancor , Curious Obsession / Curiosity etc).

If you desperately need lifegain, specific sideboard options should be more reliable- Fountain of Renewal is decent.

I'd look at alternative counter sources for Thoughtbound Phantasm and try to back it up with other efficient 1 and 2 drop threats. Blue actually has a few of these which are pretty decent- Cloudfin Raptor , Benthic Biomancer , Cosi's Trickster , Dimir Spybug , Nivmagus Elemental and Thrummingbird are all worth testing. Backing them up with some Tezzeret's Gambit can push through a lot of damage when backed by your current disruption.

If you can find a spot for them I highly recommend trying out Merfolk Trickster and Cosi's Trickster . The first is a very handy surprise (caught someone using Avacyn and trying for a onesided wrath once, great fun). The second can get big quick, especially if your opponents are fond of fetch lands. Works well with Galloping Lizrog as well.

Oh and how could I forget the new Guardian Project is perfect for this kind of high creature count deck as well of course.

Neat deck! I think you want to have all 4 Cosi's Trickster, as it's one of your best payoffs. Same thing with Lantern of Insight, it's one of the better shuffle effects just because it's only 1 mana. If you play some Field of Ruin and/or Ghost Quarter in your lands, you can have a way to force your opponent to shuffle their library while having some maindeck tron/manland hate.

With the curve he is running, 35 is generally enough. I would say add one more land but it is a minor difference. Not to mention also that Kumena himself is a draw engine, land drops shouldn't be a issue.

I do agree that for your first EDH built, it looks really solid. Some suggestions for the budget I would recommend are:

Thada Adel, Acquisitor - She can steal ramp from your opponents or just steal their things in general :P

Swift Warden - A cheap way to protect Kumena.

Jungleborn Pioneer - Makes that extra token to activate Kumena's card draw faster.

Cosi's Trickster - Just a one drop merfolk that can bigger everytime your opponents tutor.

Cursecatcher - Makes your opponent's really think about tapping out, and most of the time they forget.

Mystic Remora - Taxing card draw.

Growing Rites of Itlimoc  Flip - Budget Gaea's Cradle

Cards that I would recommend investing in getting when you have a bit more leeway with budget:

Sylvan Library: Card draw is insane, since you have low cmc you will drop your hand faster, therefore you need just as much refill.

Natural Order: Access to your more higher cost green creatures, ex. Tishana for burst card draw, Seedborn for the untaps, etc.

Hope that helps!

You can take a look at my combo version to gain more insight :p
