Tzishin, Moth Of Memories

Whenever a player discards or mills one or more
cards, you create a 1/1 blue and black Spirit Insect
creature token with haste, flying and vanishing 2.

Whenever a Spirit you control deals combat
damage to a player, that player may put three time
counters on a nonland permanent without vanishing
they control and have it gain vanishing. If they
don't, they mill four cards.
