Wicked Slumber taps down an entire board and keeps it locked with counters — the kind of swing that buys two full turns rather than one. The convoke cost makes it a genuine two-for-one on mana, and Kasla, the Broken Halo turns every tapped creature into extra value before they ever untap.

Kasla, the Broken Halo
Kasla, the Broken Halo runs Wicked Slumber because tapping a wide board is exactly the setup Kasla needs to push through damage and trigger her combat abilities unopposed — convoke lets the spell pay for itself off the creatures you're already attacking with.

Commander is where Wicked Slumber does its best work: boards get wide, convoke scales dramatically, and locking down five or six creatures with -1/-1 counters is often game-deciding. In Modern and Legacy the card is legal but rarely competitive — targeted removal or counterspells accomplish more precise work at similar or lower cost. Pioneer offers the same story: it's a slow, splash-heavy effect in a format that rewards efficiency over spectacle. Wicked Slumber is a Commander card through and through.

Price Context
Current price
$0.11 bulk tier
At $0.11, Wicked Slumber is firmly bulk — easy to pick up in any trade binder or discount bin. Bulk rare prices like this rarely move without a sudden spike in competitive play, and nothing about Wicked Slumber's profile suggests that's coming.
