"Find me cards equivalent to: Intruder Alarm"

Equivalent cards to Intruder Alarm (Enchantment, Blue, similar effect):
1. Opposition (lets you tap creatures to tap others’ permanents, still blue, disruptive)
2. Unwinding Clock (Artifacts, but only works for artifacts—closest noncreature untap effect)
3. Seedborn Muse (Green, untaps permanents on every upkeep—not blue, but similar function)
4. Back to Basics (Blue, locks lands, not creatures—not the same effect, but blue and disruptive)
5. Murkfiend Liege (Blue/Green, untaps creatures every upkeep—not quite but close)

Closest is just Intruder Alarm. There’s nothing else in blue that untaps ALL creatures whenever one enters the battlefield. Opposition is the most similar blue enchantment controlling untaps/taps.

    Rules

  • All your green and/or blue creatures untap during each other player's untap step. You have no choice about what untaps. Those creatures untap at the same time as the active player's permanents.
  • During each other player's untap step, effects that would otherwise cause your green and/or blue creatures to stay tapped don't apply because they only apply during *your* untap step. For example, if you control Nettle Sentinel (a green creature that says "Nettle Sentinel doesn't untap during your untap step"), you untap it during each other player's untap step.
  • Multiple Murkfiend Lieges are redundant when it comes to the untap effect. You can't untap your permanents more than once in a single untap step.
  • The abilities are separate and cumulative. If another creature you control is both of the listed colors, it will get a total of +2/+2.

  • Once a player announces that they’re casting a spell or activating an ability, no player may take other actions until the spell or ability has been paid for. Notably, other players can’t try to tap that player’s permanents to stop them from paying {T} or to stop them from producing enough mana.
  • You can tap any untapped creature you control to activate Opposition’s ability, even one you haven’t controlled continuously since the beginning of your most recent turn.

  • Other effects can prevent a permanent from untapping during an untap step. You do need to look carefully, however, as many effects say that the permanent does not untap during its controller's untap step, and this card's ability occurs during other players' untap steps. If a card does say this, then Seedborn Muse can untap it. But some other abilities are not written this way and can still prevent a card from untapping.
  • All your permanents untap during each other player's untap step. You have no choice about what untaps.

  • Those artifacts untap at the same time as the active player's permanents. You have no choice about what untaps and can't choose to not untap an artifact you control.
