RE: Charganium's fakes: Unown ! EX
That seems as if it could be incredibly overpowered! You could probably make a deck consisting of 4 of those, 50 Unowns and a few Psychic energies and destroy everything!
Nobody seems to care for the Unowns for a variety of factors (lame backstory, boring designs, twenty-eight forms), so card art for them is kinda slim pickings. On the other hand, I'd be willing to help if you need some artwork for any of these cards!
