Affinity is a keyword ability that reduces the mana cost of a spell by the number of permanents of a certain type that player controls. The ability is always written as "Affinity for [something]". The most common instance is "Affinity for artifacts" (see Frogmite). However, a cycle of Golems (consisting of Dross Golem, Oxidda Golem, Razor Golem, Spire Golem, and Tangle Golem) appeared in the Darksteel expansion, each with affinity for a particular basic land type.
