Glava, Five-Advents Mage

Whenever you cast a permanent spell with {X} in its mana cost or activate an ability with {X} in its activation cost that isn't a mana ability, you may have the value of X become 5. Do this only once each turn.

"The Third Advent brings hunger. Feed it, but never sate it. Hunger begets growth." —*Path of the Pentarch*
