Valyncia, Sky-riding Lancer

Flying
When Valyncia, Sky-riding Lancer blocks or
becomes blocked, until end of the phase,
creatures fighting her lose all abilities, and for
each ability lost this way Valyncia gains another
ability of your choice of first strike, lifelink or indestructible. (An ability can be any paragraph of
text ending with '.', or an evergreen ability.)
