Affinity

Keywords · beginner

Affinity reduces a spell's cost based on what you control. It reads "Affinity for [something]," most commonly "affinity for artifacts."

How it works

• The spell costs {1} less to cast for each matching permanent you control.
• With affinity for artifacts and five artifacts in play, the spell costs {5} less.

Rules notes

• Affinity only reduces generic mana. It can never reduce a cost below its colored requirements.
• The reduction is calculated as you cast the spell, based on what you control at that moment.
• Affinity does not change the spell's mana value.
