Pokemon Pal City also did this a few years later
As far as a rating goes I would rate this card a 2 out of 5 because it really isn't that good, it has a low hp for a stage 1 Pokemon card, and Fairy Power is a good move but I could see this move actually being a Poke-Power on a Pokemon, there is no way this move should cost two colorless energy cards, by the time you get two energy cards on Clefable you more than likely are going to be able to retreat one Pokemon two your hand before Clefable gets knocked out so there is really no point in using that move at all, unless the Pokemon you want to retreat is really that powerful and can create massive amounts of havoc if it is fully recovered
Their first opponent was Tetsu Trudge, but the twins defeated him with ease
The deck can go into many powerful extra deck monsters like: Chaos Ruler, the Chaotic Magical Dragon Baronne de Fleur Apollousa, Bow of the Goddess Borreload Savage Dragon Supreme King Dragon Starving Venom This deck has many variations and can even be mixed in with a few smaller engines like the Destiny HERO - Destroyer Phoenix Enforcer engine if the deck feels like it's lacking in power or consistency
That casting cost can be a bit prohibitive (splashing it in Limited won't be super easy), but in a White / Green build this 4/4 first striking, trampling construct hits hard
