Thief of Sanity

Thief of Sanity

Creature — Specter

Flying

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

Tylord2894 on Mutations and thief of sanity ...

3 days ago

The reminder text for Mutate doesn't fully explain the requirements of a mutate spell (as seen on something like Cloudpiercer). The rules for mutate state it much more clearly. “Mutate [cost]” means “You may pay [cost] rather than pay this spell’s mana cost. If you do, it becomes a mutating creature spell and targets a on Human creature with the same owner as this spell.” (702.139a).

Since you don't own the mutating creature spell, it can't target non-Humans that you own. So, it is not a bug and is working as intended. That said, if you gain control of a non-Human your opponent owns (either through Thief of Sanity or another effect), you can mutate onto that card.

Hope this helps!!

Supersaulty on Mutations and thief of sanity ...

On MTGA when I steal a creature with mutation with my Thief of Sanity it won't let me mutate a creature I OWN, but, it will let me mutate a creature I control that my opponent owns... Is this a bug in MTGA? Curious for tabletop.

I feel kinship with a lot of cards. Some of them are... Xantcha, Sleeper Agent, Yarok, the Desecrated, Thief of Sanity, Gargos, Vicious Watcher, Helm of the Host.

Thief of Sanity Sounds quite good. I Wish it would say "Play" rather than "Cast" but might be worth a shot.

Mnemonic Betrayal gets you ramp If you have some Mana available. Since Niv never hits lands it's quite important to get your Lands/Ramp somehow. But yeah sometimes it's just not worth casting.

Jodah and Fist aren't for this Deck, as you mentioned, not 2 colored.

Jegantha works well for fixing for Niv, If you have 5 Lands but not 5 colors, jegantha comes in Handy

Mnemonic Betrayal is almost always dissapointing for me. Fist of Suns and Jodah, Archmage Eternal are good with Jegantha, but not grabbable with Niv, so they might not be worth it. The deck might want Thief of Sanity because it takes Betrayal's slot and does something similar. It does die to removal, so it might not be the best.

Tylord2894 on "Gain Control" Rulings

4 weeks ago

While Gilded Drake's effect doesn't end when the Drake leaves the battlefield, that effect is notably different from that of Bribery.

The effect from the Drake creates a continuous effect that gives you control of the target creature and gives your opponent control of the Drake.

On the otherhand, Bribery puts a card from an opponent's library onto the battlefield under your control. At no point is control of that creature changed. This is similar to how Thief of Sanity would work in this case. Since there are no control effects to dispell, the creature that you gained is exiled.

That make sense?

Yes, but Thief of Sanity only triggers when I deal player damage. What should I replace with Tyrant's Scorn and Drown in the Loch?

Ninjew42 on Sadomasochistic Thirst of Libraries

Also, Thief of Sanity triggers any time it does combat damage, and you get a card from their deck that you can cast. Minister of Inquiries can only mill 6 unless you bounce him or have a way to make more energy.
