Melanie, of Past and Future

When Melanie enters the battlefield, attacks, or blocks, Find the Egg.
Whenever you Find the Egg, you draw a card.
Melanie's power is equal to the number of star counters among permanents you control.
When Melanie dies, you may remove three star counters from among permanents you control.
If you do, return her to the battlefield tapped at
the beginning of the next end step.
At the beginning of each end step, if you don't
control an artifact named The Egg, exile Melanie.
