The front face gets back a nonbattle permanent which is something that white and black can do when combined (white can get back artifacts, enchantments, lands, planeswalkers, and small creatures, while black can get back creatures of any size)
It's only got 1 power, so there's a good chance it won't get blocked, and it can draw you a card (at the cost of 1 life) when it attacks
Notably, opponents can't try to remove a creature after choosing it but before you gain control of it
By presenting this card, you may gain preferential entry into the Secret Super Battle. The No.1 Trainer card features the Japanese logo for the Pocket Monsters Trading Card Game and illustrator Hideki Kazamas incredible Mewtwo art too
Its great for redirecting damage, or making your heavy hitter into an unstoppable machine
