  Official Ruling
  If a spell has multiple instances of affinity, each one applies. For example, if you somehow control two Witherbloom, the Balancers and no other creatures, each instant and sorcery spell you cast will cost less to cast.

  Official Ruling
  To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell remains unchanged, no matter what the total cost to cast it was.
