Decoction Module⁣ - Kaladesh⁣ (Uncommon)⁣ [205]

Decoction Module is a two-mana artifact from Kaladesh that generates an energy counter each time a creature you control enters the battlefield. Its activated ability allows you to return a creature to your hand for four mana and tapping the Module, making it useful for recycling creatures with enter-the-battlefield effects or protecting key threats. This card fits well in energy-based strategies or decks that focus on creature synergies, although its mana cost for the ability can be a limiting factor.
