Minfilia Warde

If Minfilia Warde is your commander, you
may start the game with "The Mothercrystal"
card on your battlefield.
Scions you control gain Vigilance.
During your upkeep, you may draw a card for
each Scion you control, then discard that many
cards from your hand. Any scions that are
discarded by this effect are instead shuffled into
your library.
