Corrin, Dragon Form Warrior

When Corrin deals combat damage to a player,
put a spage counter on target creature. Creatures
with spage counters on them cannot untap
during their controller's turn or during upkeeps.
At the beginning of your upkeep, you gain a life
for each tapped creature. If there are ten or more tapped creatures, you may draw a card.
Corrin can't be blocked.
