Phelaphus, the Dissenter

Merfolk spells you cast cost {1} less to cast for
each merfolk spell you have cast this turn.
At the beginning of your upkeep, you may gain control of target artifact or enchantment with converted mana cost equal to or less than the number of merfolk you control until end of turn, unless you control 5 or more merfolk.
