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.

The suspend cards would be unplayable in the given scenarios.

Suspend only works from your hand; it is not available as an alternative means of casting a spell in any zone other than your hand.

Cards with no mana cost such as Wheel of Fate can't have their mana costs paid, so they would only work with abilities that allow you to cast them "without paying their mana cost."

In the case of Experimental Frenzy , the card is in your library, not your hand, so you can't suspend it, and you can't play it by paying its mana cost because it has none.

Light Up the Stage and Thief of Sanity both put the card into exile, so you can't use suspend from there, and again, you can't pay a mana cost that doesn't exist in order to cast the card from the effect's normal means.

So you can't cast it for 0 or suspend it.

I'm curious about the rules for casting or suspending cards without mana costs like Wheel of Fate .

Can I cast this card off the top of my library with Experimental Frenzy ?

Can I cast this card from exile with Light Up the Stage ?

If I put this card under Thief of Sanity can I cast it?

And for all of the above scenarios, can I cast it for 0 or do I have to suspend it?

Thanks in advance!

You can also use Might of Old Krosa but it's a bit more expensive so I don't run it. Underrated card of the day: Thief of Sanity

Hi there.

Fun idea you have here. Loved playing Thief of Sanity , when it was viable in GRN Standard.

A few suggestions:

  • Bontu's Last Reckoning is quite horrible here, as you will technically take a turn off when you play it early, giving those aggro decks lots of time to rebuild. I'd play something like Languish instead. If you think you'll get run over by some hyper-aggro, how about Cry of the Carnarium ? Incidentally it also deals with most Aristocrats decks, as they don't get any on-death triggers.

  • Murderous Rider is mostly better than Hero's Downfall . Both because of the added value after you remove something, but also because it can be a creature in a pinch or when you have no targets (which does come up occasionally). I know it doesn't tigger God-Eternal Kefnet , but that's a small price to pay.

  • Fatal Push can do a lot against those pesky aggro decks. I'd cut some number of Cast Down and/or Tyrant's Scorn to make room for them.

Good luck!

Maybe Primal Amulet  Flip would be good for the deck since you've go a bit of a spellslinger build going on.

Then you've got Hostage Taker and Thief of Sanity as creatures who can steal more cards.

I have replaced Wrexial, the Risen Deep with Thief of Sanity , which lowered the average converted mana cost of this deck from 4.40 to 4.35, which is good, and I also feel that the thief's ability better fits the controlling theme of this deck.
