Spire Serpent

Creature — Serpent • Mana cost: {4}{U} • Mirrodin Besieged • Common

Defender
Metalcraft — As long as you control three or more artifacts, this creature gets +2/+2 and can attack as though it didn't have defender.

A mirror to draw its eye, a rod to rouse its rage, and a sword to break its bonds.
