Myr Rho Blood Hunter

{1}: Pair this card with another Cathar you
control. They both get +1/+1 as long as you
control both of them and they remain paired.
They remain paired and cannot be paired with
other creatures until one of them leaves the battlefield. Pair only as a sorcery.

Celebration—If one or more permanents entered
the battlefield under your control this turn,
Myr Rho Blood Hunter gains double strike
until end of turn.
