Magic Card

From MMKB

Magic Card is Magic Man's weapon. It's a card that can shoot out to hit enemies and boomerang back. As a bonus, it can even snatch items that are out of reach, whether too high, too far away, or too dangerous to reach for. It can be directed upwards, as well. When Magic Man uses it, he can steal your health and use it to heal himself. It's very effective against Astro Man, since not only is it his weakness, Astro Man usually stays out of reach of attacks, and Magic Card can hit him from below.
