Violet Lotus Cloak

At the beginning of your upkeep, if your
commander is in the command zone, you may
put a storage counter on target land.
Lands you control have: "{t}, Remove X
storage counters: Add X colorless mana. If X is
greater than 5, you may instead add X mana
of any combination of colors. Use this mana
only to cast your commander."
(Your commander may normally bear only one of
each type of Regalia.)
