- If Wondrous Labyrinth {*} stadium is in play, how many energy are needed for energyless attacks?
- Any attacks that normally cost no energy now require at least one energy to be attached when Wondrous Labyrinth {*} is in play. However, if an effect like Persian's "Gathering of Cats" Ability sets an attack's cost to zero energy, Wondrous Labyrinth {*} does not add an additional energy requirement to it.
