"Find me cards equivalent to: Secrets of the Key"

Here are a few cards similar to Secrets of the Key with the same color (U), instant type, and that investigate or make Clue tokens:

  • Compelling Deterrence — Instant, U, interacts with clues if you control a Zombie.
  • Confront the Unknown — While not blue, it’s a close equivalent in function (but green).
  • Whir of Invention — U, instant, makes an artifact, but not a clue.

Closest in blue that investigates at instant speed is Secrets of the Key itself—other blue investigate cards like Press for Answers are sorceries. No exact functional instant, blue, investigate alternative exists.

  • Compelling Deterrence checks to see if you control a Zombie after the target nonland permanent is returned to its owner’s hand. For example, if you target the only Zombie you control with Compelling Deterrence, you won’t discard a card.
  • If the target nonland permanent is an illegal target as Compelling Deterrence tries to resolve, it won’t resolve and none of its effects will happen. No player will discard a card.
  • The card returned to its owner’s hand may be the card they discard. If it’s the only card in that player’s hand, it must be discarded if you control a Zombie.

    Investigate

    Rules

  • Clue is an artifact type. Even though it appears on some cards with other permanent types, it's never a creature type, a land type, or anything but an artifact type.
  • If an effect refers to a Clue, it means any Clue artifact, not just a Clue artifact token. For example, you can sacrifice Wrench to pay for Alquist Proft, Master Sleuth's activated ability.
  • No player may take any action in between the two steps of Confront the Unknown, so the target creature will get at least +1/+1.
  • You can't cast a spell without choosing legal targets. If all of those targets become illegal, the spell doesn't resolve and you won't investigate.
  • You can't sacrifice a Clue to pay multiple costs. For example, you can't sacrifice a Clue token to activate its own ability and also to activate Alquist Proft, Master Sleuth's ability.

    Flashback Investigate

    Rules

  • "Flashback [cost]" means "You may cast this card from your graveyard by paying [cost] rather than paying its mana cost" and "If the flashback cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack."
  • A spell cast using flashback will always be exiled afterward, whether it resolves, is countered, or leaves the stack in some other way.
  • If a card with flashback is put into your graveyard during your turn, you can cast it if it's legal to do so before any other player can take any actions.
  • To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.
  • You can cast a spell using flashback even if it was somehow put into your graveyard without having been cast.
  • You must still follow any timing restrictions and permissions, including those based on the card's type. For instance, you can cast a sorcery using flashback only when you could normally cast a sorcery.

    Improvise

    Rules

  • Because improvise isn't an alternative cost, it can be used in conjunction with alternative costs.
  • Equipment attached to a creature doesn't become tapped when that creature becomes tapped, and tapping that Equipment doesn't cause the creature to become tapped.
  • If an artifact you control has a mana ability with {T} in the cost, activating that ability while casting a spell with improvise will result in the artifact being tapped when you pay the spell's costs. You won't be able to tap it again for improvise. Similarly, if you sacrifice an artifact to activate a mana ability while casting a spell with improvise, that artifact won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for improvise.
  • Improvise can't be used to pay for anything other than the cost of casting the spell. For example, it can't be used during the resolution of an ability that says "Counter target spell unless its controller pays {3}."
  • Improvise can't pay for {W}, {U}, {B}, {R}, {G}, or {C} mana symbols in a spell's total cost.
  • Improvise doesn't change a spell's mana cost or mana value.
  • Tapping an artifact won't cause its abilities to stop applying unless those abilities say so.
  • When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Improvise applies after the total cost is calculated.
  • When using improvise to cast a spell with {X} in its mana cost, first choose the value for X. That choice, plus any cost increases or decreases, will determine the spell's total cost. Then you can tap artifacts you control to help pay that cost. For example, if you cast Whir of Invention (a spell with improvise and mana cost {X}{U}{U}{U}) and choose X to be 3, the total cost is {3}{U}{U}{U}. If you tap two artifacts, you'll have to pay {1}{U}{U}{U}.
