Is Azuki’s Sealed IKZ like Overload in Hearthstone?
MostlyMostly. Both let you play an undercosted card this turn by locking mana or IKZ through your next turn’s refresh.
Sealed in the Azuki TCG
A Sealed IKZ is a tapped IKZ resource that cannot be untapped until after your next Reset phase (your start-of-turn untap). Mirrored Reflection plays a Water entity costing up to 5 for 3 IKZ now (while letting your opponent play an entity costing 5 or less into their Alley), then Seals 2 of your tapped IKZ so they skip your next Reset phase.
The same
- You get full board impact a turn or two early and pay the rest of the cost out of next turn’s resources.
- Locked crystals and Sealed IKZ stay unusable through the next turn’s normal refresh.
Different
- Hearthstone Overloaded Mana Crystals stay locked for your entire next turn unless unlocked by specific Overload synergy cards like Overdraft. Under Azuki’s November 20, 2026 Mirrored Reflection errata, Sealed lasts only until after your next Reset phase: Hydromancy Gate cannot untap Sealed IKZ on the turn you cast it or during that Reset phase, but once your next Reset phase finishes, Sealed clears and manual untap effects on that turn can refresh those tapped IKZ.
- Mirrored Reflection also gives your opponent a symmetric window to play an entity costing 5 or less into their Alley; Hearthstone Overload cards don’t give your opponent anything.
