Upgraded

• Cost: 1
• Effect: Whenever you apply Decay, gain 3 Block.

A passive Power that hands out Block every single time Decay is applied. In Decay decks that apply Decay many times per turn, a 1-cost investment turns into a tidal wave of Block across a combat.

Combine with Deathbringer (21-26 Decay to all), Negative Wave (7-11 Decay to all), Nowhere to Run, Countdown, Oblivion — any of the many Decay applicators — and 30-60 Block in a single turn becomes realistic. The core self-contained synergy of Decay decks: the faster you attack, the harder you turtle. A must-include Power.

Rating: S-tier (defensive cornerstone of Decay decks, 1 cost for enormous combat-long Block)

• Drop early so every Decay-applying card auto-stacks Block
• Against multiple enemies, Deathbringer / Negative Wave grant enemy count × 2-3 Block at once
• Upgraded 3 Block means 10 Decay applications = 30 Block, a truly elite defense
• With Countdown (auto 6 Decay at turn start), Cloak grants Block every turn for free

• Deathbringer: 21-26 Decay to all. 3 enemies = 6-9 Block in one play
• Negative Wave: Decay + Block to all enemies. Stacks additional Block with Cloak of Shadow
• Nowhere to Run: huge Decay applications drive huge Block. Decay stacks = Block spikes
• Countdown: turn-start Decay 6. Auto 2-3 Block every turn
• Oblivion: Decay 3 per card played. Every play = +2-3 Block stacking
