A Charm is a modal instant spell with three possible results of which one can be selected. Charms usually appear in horizontal cycles. So far there have been charms at common that cost a single colored mana, charms at uncommon that cost three different colored mana centered around one color with its two allies and charm at uncommon costing two colored mana. According to Mark Rosewater, players like these Charms and he is pretty sure we will see them again.
