Phyrix, the Martyr

When Phyrix the Martyr dies and does not have a +1/+1 counter on it, return it to the battlefield during your next upkeep and put 2 +1/+1 counters on it.
If Phyrix the Martyr has a +1/+1 counter on it, it gains double strike.
Phyrix gave up her life in defiance of the Lady's will. She has given her life far more times in service to her.
