The battle of the two Psychic-type mistresses! They both have three stages in their evolution families, though Ralts's is split; they can learn similar standard attacks of the type, and they are both charming in their own ways.
Which do you think will win, be it for design, attachment, usefulness, stats, etcetera?
I personally prefer Gochiruzeru. It has a wider movepool, better and more balanced defenses, useful for detecting objects in battle (which may or may not be stolen afterwards), the Dream World ability is awesome too, and I like its darker design.
