Its a fantastic card, and given that you can buy the non-Enchanted version for under $5 , it feels like its worth building a Ruby deck just to test him out
Here the clue is just gravy for recurring your permanents, but that's also a good example of what makes Clues such a great design tool: Anything is better with card draw added
Mew is classified as a 3-Stars card in the Mega Shine set
Whether you're playing it in Control, Bant Field of the Dead, Esper Planeswalkers, or whatever other deck you're running, or your building your deck against it, be ready for Supreme Verdict with other countermeasures like Selfless Spirit or be ready to build a threat base that mixes in other threats like planeswalkers or vehicles to help insulate yourself
Yeah, theres still a bit of guess work left, such as with the Weakness and Retreat Cost and the Pokmon 25 logo but still, there is a LOT removed from just mixing those cards together, and whats left is damn near trivial to remove
The most logical next step would be a set focusing on Generation 2, with the featured Pokmon potentially being Tyranitar, Umbreon, or even one of the Legendary Beasts like Suicune
