Copy Flower

Copy Flowers are two-headed flowers found in Mario & Luigi: Partners in Time. When either of the brothers uses it, the four heroes get multiplied to massive numbers. Then, all of the clones run and jump on the enemy. You must press each of hero's separate buttons to deal damage to the opponent. Although there only seems to be a limited number of clones upon use, the number of them never seems to run out, though they can all disappear if the action command is failed, or the enemy is defeated.

If the 4 have very high attack power, this item can do quadruple-digit damage if executed superbly. Good 'stache could work to their advantage as well.
