 * this turn if able. These effects are applied after all other continuous effects have
 * been applied. Continuous effects that affect the costs of spells or abilities are
 * applied according to the order specified in rule 601.2e. All other such effects are
 * applied in timestamp order. See also the rules for timestamp order and dependency
