Thief of Sanity

Thief of Sanity

Creature — Specter


Whenever Thief of Sanity deals combat damage to a player, look at the top 3 cards of that player's library. Exile one of those cards face-down, then put the rest into that player's graveyard. You may look at and cast that card for as long as it remains exiled, and you may spend mana as though it were mana of any colour to cast that spell.

Thief of Sanity Discussion

dragonstryke58 on Chandra Heart of Fire

I think a better example to contrast the ability of Chandra, Heart of Fire would be Thief of Sanity.

Each card exiled by the abilities of both Chandra, Heart of Fire and Thief of Sanity contain a time duration in their effects that stipulate when you can use the effect. In the case of Chandra, Heart of Fire, the duration is "until end of turn". For Thief of Sanity, the duration is "for as long as this card remains exiled".

The part you are confusing is that "you may play cards exiled this way" means that exact instance of the effect. It is similar to how the effects of permanents that name themselves mean this specific permanent and not all permanents with the same name.

you'll probably get at least 1 activation off of it all the time. at that point it's 3 mana to ensure you're building your board next turn.

consider you're almost certainly playing it on a creature that already has a counter on it, and so if they waste removal on it then that's fine since now they don't have removal for something that matters and you have essentially only lost 3 mana since your creature is just coming back.

consider also that they've had removal and they haven't used it on whatever you're playing shadow on so far, so it's probably not a big threat to them, so why would they waste a removal spell on it? they'll probably save it for whatever comes out off of shadows next turn if it even is a big immediate threat to them.

are you going to really lightning bolt my Baleful Strix or Solemn Simulacrum (with a +1/+1 counter on it probably) just because it has Shifting Shadows on it? probably not.

shadows triggers and now I have a simulacrum + a Thief of Sanity do you want to use your removal on either of them really? maybe, but they might say ... well this isn't that bad, i'll wait till something ACTUALLY bad comes out and then i'll kill it. and by then you've gotten 3-4 free creature tutors.

it's somewhat of a damned if you do damned if you don't card for your opponents and it has a low opportunity cost for you.

I think it's a good card, but I ended up going for Imperial Recruiter instead since it lets me have more choice over what cards I'm getting.

all of your concerns are totally real, and you should be aware of them and let that influence how you play the card. (like by not putting it on creatures without evasion, or on high priority for removal creatures, or saving a counter spell in case you get something really good off it) that said, I still think it's generally a good card.

CMC 10 Planeswalker? How about a Phyrexian Ashiok? That's where they want to be anyways

Ashiok the Interloper

Legendary Planeswalker - Ashiok

+2: Exile the top card of each library.

0: Until end of turn, you may play up to one card an opponent owns in exile without paying its mana cost.

-4: Create a 2/2 blue and black Specter creature token with flying and "Whenever this creature deals combat damage to a player, that player exiles the top card of their library."

-24: Exile each opponent's library.


Yeah, I think this would be very fun, but not OP at all. Yeah, you get a Nightveil Specter/Thief of Sanity with the -4, but it's a very expensive walker and without adequate set up, the 0 doesn't do much. The +2 isn't really going to do much without some sort of payoff, but it does help the 0 and reaching the ult, which is basically an instant game-winner.

Yo where is Hostage Taker and Thief of Sanity

SynergyBuild I agree that Naya shouldn’t mill the cards to the grave but cards like Militia Bugler have similar effects.


Just throw them to the bottom like Bugler, lol.

As far as suggestions go, I would love to see a Viking in a similar vein but they “kidnap” enemy creatures. Something like Thief of Sanity but only for creatures.

Idk how you flavorfully fit that into Naya however lmao, good luck.

While I fully understand (and agree) that Thief of Sanity is super strong, I do agree with a few others that it is relatively vulnerable... is Ashiok, Nightmare Weaver a better option? In the very least, she has an immediate effect once she hits to guarantee 3 cards in exile, and when your opponent works on removing her you're either saving yourself life points, or, they're using the same resource to kill her as they would the Thief.

I know you said it isn't meant to be a controlling deck, but functionally, the two cards are very similar... one just has more toughness (unless they have exactly Dreadbore).

RocketUserPro I'm pretty sure I have a Reclamation Sage somewhere so I'll add that. Thief of Sanity is there mainly because I'm greedy and I get Guardian Project triggers off of it with added value. I did notice when making this deck that the land count is very low and that's why I posted the deck here. I'll consider Master Biomancer but Panharmonicon is a bit out of reach for me right now. Maybe in the future. I'll probably cut Void Winnower once I've made my death and taxes deck. What would you recommend I do for adding lands? Thank you for all of the criticism! It's really appreciated.

I'll share my experience with you. I tried a competitive UB mill in Pioneer for a while, but it was far too slow. There are not many great mill cards in Pioneer. So, I changed my build to combo-based with 4 Fraying Sanity and 4 Traumatize. And it started to work.

It made a great difference and I started to win. I play now Thoughtseizes, Bontu's Last Reckonings, sideboard Leyline of the Void, Fatal Push...

I think you oughta try and see for yourself. Because, let's be frank Mind Sculpt is pretty meh. And the 0/4 creatures to stop aggro don't always do the job. The only real good card is Thief of Sanity and even him is too vulnerable. The opponent won't waste removal on a wall if he can wait to target the Thief.

My best bet is that the best version of this deck is focused on combo and a possible alternate wincon with a planeswalker or a manland. Think of all the slots you'll free if you abandon the non-combo mill cards and how much you'll gain by adding cards like Cry of the Carnarium, Languish, etc.
