Training Drone⁣ - Mirrodin Besieged⁣ (Common)⁣ [142]

Training Drone is a 4/4 Artifact Creature that cannot attack or block unless it has an Equipment attached to it. When you play this card for three mana, you're essentially getting a hefty creature, but its inability to participate in combat without being equipped can be a significant drawback. You'd want to use Training Drone in a deck that focuses on equipping creatures, as it can become a strong attacker or blocker with the right gear, but be cautious of the fact that it sits idle without those attachments, making it less effective in the early game or against aggressive opponents.
