text: Effects that reduce the generic mana cost of an activation cost can't reduce that cost's colored mana requirements. The activation cost is reduced by only {1} if doing so reduces that cost to one mana. For example, a cycling cost of {2} would become {1}, and one of {1}{R} would become {R}. The activation cost is unaffected if it already costs one or zero mana (such as the activation cost of Zirda's last ability).
