Nirvana

Nirvana is a Watcher uncommon power that grants 3 Block every time you Scry for 1 energy. The Watcher has multiple Scry effects — Cut Through Fate, Third Eye, Just Lucky, Foresight, and others — so Nirvana converts that existing Scry activity into passive Block generation. Each individual Scry event triggers Nirvana independently: Scrying 3 with Third Eye triggers Nirvana 3 times, giving 9 Block. In Scry-heavy builds, Nirvana provides enormous Block per turn.

Nirvana's ceiling is reached in decks built around multiple Scry effects. Combined with Foresight (Scry 3 per turn) and Cut Through Fate (Scry 2 per play), you can generate 15-25 Block per turn purely from passive Scry triggers. This creates a tank archetype where your Block sustain is driven entirely by deck manipulation rather than traditional defensive cards. Multiple copies of Nirvana stack, doubling or tripling the Block per Scry. Upgraded, Nirvana grants 5 Block per Scry instead of 3, dramatically increasing the Block generation rate.
