Metallicize

Metallicize is a 1-Energy Ironclad Power that grants 3 Block at the end of every turn (5 upgraded). The passive, recurring Block is the draw — once played, Metallicize provides 3 free Block every single turn for the rest of the fight without any additional investment. Over a 5-turn fight, that's 15 free Block total; in a long boss fight it can contribute 30+ Block purely from this one Power.

Metallicize is a "set it and forget it" defensive tool that works in any Ironclad build. The earlier you play it, the more cumulative value it provides. Upgraded at 5 Block per turn, a long fight produces substantial passive defense. It also pairs well with Barricade (retained Block compounds with each turn's addition) and any deck that wants consistent baseline protection.
