Huma Dragonbane

Vigilance, Firststrike
When Huma Dragonbane enters the battlefield
tap all dragons your opponents control. They
don't untap during their controller's untap step.
At the beginning of each opponent's upkeep they
may pay {2} for each dragon they wish to untap.
Other knights you control have +1/+1, vigilance.
Est Sularis Oth Mithas in the old tongue.
