let's be honest. the card BY ITSELF isn't promising. 90hp basic, 20 for 2 with a possibility of 60, 2 retreat, a 2x psychic weakness, and a body that's just like Unown G.
however, if you are just playing this card alone, there's something wrong with you...
Combo'd with Skuntank, you get an always 60 for 2, or 1 with Energy Gain, because it's SP you can use cards like Power Spray, it's basic so can be nabbed with Rosy, with snowpoint it gets 110hp, Cyrus's Conspiracy adds HUGE support, can be grabbed with Weavile G, and in the upcoming sets we will see MASSIVE SP support cards.
Tier 2 definitely, with upcoming sets we will see plenty of SP, all in all i feel this card gets a:
8.5/10-lots of combos to it, has the donk factor, but isn't unstoppable. Then again, that's been the definition of this year's Metagame so yeah.
