Don't forget that making tokens is going to count, as this is not a cast trigger, unlike Karametra, nor is there a "nontoken" restriction written into the card
To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of Urianger Augurelt's last ability)
For example, if Prowler is blocked by a creature with 4 power, and then an effect gives that creature -3/-0, it won't stop blocking Prowler
The low stats mean that Pinocchio, Star Attraction isnt especially survivable or worth using in a challenge, so its really that massive lore gain were looking at here
Timing rules still apply.) You have a lovely face
