Power-upPower-up is a keyword that adds additional rules to the activated ability that follows it. “Power-up — [Cost]: [Effect]” means “[Cost]: [Effect]. If this permanent entered this turn, this ability’s cost is reduced by this permanent’s mana cost. Activate this ability only once.”
Generic mana in the permanent’s mana cost reduces generic mana in the cost to activate its power-up ability. Colored and colorless mana in the permanent’s mana cost reduces mana of the same type, and any excess reduces that much generic mana. (See rule 118.7.) (CR 702.193) —

(CR 701.7) The Tiger God, a legendary 4/4 green Cat God creature token with "The Tiger God can't be blocked by more than one creature." (
ActivateTo activate an activated ability is to put it onto the stack and pay its costs, so that it will eventually resolve and have its effect. Only an object’s controller (or its owner, if it doesn’t have a controller) can activate its activated ability unless the object specifically says otherwise. A player may activate an ability if they have priority. See rule 602, “Activating Activated Abilities.” (CR 701.2) each
