Ke'Calas, First of Ovi

Flying, First Strike
When Ke'Calas attacks, you may pay {w}{u}{x}. If
you do, X target creatures cannot block Ke'Calas
this turn.
The Ke of the Ghedwi are master tacticians, blessed
by the spirit Ovi. The current Ke dedicates their life
to supplying the Ghedwi with every possible advantage
against the foretold Last March of Dur Amoruk.
