Reiked, the Indebted

At the beginning of your upkeep, place a Debt counter on
Reiked, then choose one:
• Draw a card.
• Gain three life.
• Target player loses three life.
{bull} Reiked gains +3/+3 until end of turn.
{bull} Reiked gains flying and lifelink until end of turn.

During each opponents combat phase, that player creates an
X/X white and black Spirit creature token tapped and
attacking you, where X is the number of Debt counters on
Reiked. Exile that token at the end of combat.
