The original also had Polukranos at mythic and another hydra at rare
As to the composition of the full art Trainers/secret rares sheet, this is the third and final Sun & Moon set for which my model assumes different rarities for the secret rares (the other two being Sun & Moon Base Set and Celestial Storm) as this model seems to best fit the raw data: each of the 6 full art Trainers printed 5 times on the sheet, 10 of the 20 secret rares 4 times and the other 10 3 times
A creature like Duskwatch Recruiter with a good mana sink ability is also very useful in a werewolf deck
Dark decks also work very well with Gold-Plated Cables, since having the rightmost Dark orbs passive activate twice can build up damage twice as quickly
Like most Pokmon cards, the value of Mewtwo depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Legends Awakened)
That Set card can be activated during this turn
