Players can cast spells only during their own turns.
"Each night as Master Dosan prays to the kami, the hate he receives in return withers his body a little more. Though the kami are slowly killing him, still he continues his prayers."
—Meditation journal of a young budoka
Whenever you cast a Spirit or Arcane spell, you may put a ki counter on Faithful Squire.
At the beginning of the end step, if there are two or more ki counters on Faithful Squire, you may flip it.
At the beginning of your upkeep, if Genesis is in your graveyard, you may pay . If you do, return target creature card from your graveyard to your hand.
Gain control of target creature until end of turn. Untap that creature. It gains haste until end of turn. If that creature is a Goat, it also gets +3/+0 until end of turn.
Target creature you control climbs into Goblin Sleigh Ride. You slide them on their merry way. If the creature stayed on, it deals damage equal to its toughness to each other creature touched during the slide.
