Rulings
- 2011-06-01:
Spire Serpent still has defender if you control three or more artifacts, although it will be able to attack.
- 2011-06-01:
If Spire Serpent has been declared as an attacker, and you stop controlling three or more artifacts later in combat, Spire Serpent continues being an attacking creature until combat ends.
