3 rulings from Wizards of the Coast
- 1 December 2004The spells gain affinity for artifacts as they’re put onto the stack. They don’t have the ability while they’re cards in your hand.
- 1 December 2004Two or more instances of the affinity ability are cumulative, even if they’re both affinity for the same thing.
- 1 December 2004If Mycosynth Golem is sacrificed as part of the cost to cast a spell, the cost reduction will already be locked in, and the cost won’t be increased.
