Cumulative upkeep {1} (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.)

Artifacts and lands enter tapped.

Each noncreature artifact loses all abilities and becomes an artifact creature with power and toughness each equal to its mana value. If this enchantment leaves the battlefield, this effect continues until end of turn.
