Encantamiento — Aura
Encantar permanente.
Al comienzo de tu fase principal precombate, agrega maná igual al coste de maná del permanente encantado a tu reserva de maná. (El coste de maná incluye el color. Si un símbolo de maná tiene varios colores, elige uno.)
This ability isn't a mana ability. It uses the stack.
Only the first main phase in a turn is the "precombat main phase," even if additional main phases are generated by some effect.
You get the mana whether you want it or not. If you don't spend it, it will disappear at the end of the current step (or phase).
