Manahive

Equivalent cards to Oxidda Golem (colorless artifact creature with affinity for mountains):
1. Myr Enforcer – Artifact Creature, Affinity for artifacts, 7 mana, 4/4.
2. Somber Hoverguard – Blue Creature, Affinity for artifacts, 6 mana, 3/2, flying.
3. Frogmite – Artifact Creature, Affinity for artifacts, 4 mana, 2/2.

Reason: All are affinity creatures from the same era, and Myr Enforcer is closest because it's colorless like Oxidda Golem.
