Retreat cost/Effects that alter Retreat Costs

Several Pokémon are capable of altering retreat costs, usually through Pokémon Powers. In most cases, increases in retreat costs are done by fixed amounts, while reductions may be either fixed amounts or decreases to 0. Increases are calculated first, meaning that if an increase to the retreat cost and a reduction of the retreat cost to 0 affect the same Pokémon, the Pokémon's resulting retreat cost is 0.
