Queen Mirabella Terrasen

Hexproof
Knights gain Loyalty: While a Terrasen creature
is in play, creatures can trigger Loyalty. Without
one, Loyalty cannot be triggered. When creatures
with Loyalty block or attack a creature with
higher power or toughness, they gain first strike
and +2 +2 for each Terrasen creature in play.

The King kept the order, but the Queen kept the love
of the people.
