You may sacrifice a creature named Mareep rather than pay this spells mana cost.
At the beginning of your upkeep, get {e}{e}.
As long as you control a (-) creature, damage dealt by sources you control which cost {e} deals that much damage plus 1 instead.
{p/g}: Flaaffy gets +0/+2 until end of turn.
{t}, Pay {e}: Flaaffy deals 5 damage to target attacking or blocking creature.
