The pokemon that really caught my attention here was Golem. With its double throw, it is like dual splash with +1 energy. It also has the option of 80, or reducing by 40, which is pretty good. My brother won states with the card and me and my friend (dudeman) were in awe.
Anyways...The other cards are really not very good. Lets start from the bottom:
Aerodactyl: Good tech, should be played as a tech, and nothing more.
Lapras: ONLY good as a starter, so unless you get it, it just takes up space
Exploud: slow. 1st attack is decent, but 4 energy for a mere 70 damage is not impressive.
Weavile: Asi-Asi (spanish for OK). Depends on how you play it, but most of the time it is Asi-Asi
Gengar: Great for reducing HP, but very flippy. By the way, combo? Also, it the defending pokemon has 10 HP left, life drain does 0, same if you add plus power, so it is not very good...
Now I hope you know why these are not in the Meta game, and why they may never be. But i like your ideas!
