Blademaster Bolvyn

First Strike
At the end of your turn, if you attacked with a creature this turn, you may reveal Blademaster Bovyn from your hand. If you do, put a Rally counter on him.
Blademaster Bovyn has +1/+1 for each Rally counter on him.
If Blademaster Bovyn has five or more Rally counters on him, he gains Indestructible.
