Feisty Mongoose

As long as you control a Desert, Feisty Mongoose
has hexproof.
{1}{b}: Feisty Mongoose gets +1/+0 and gains
first strike until end of turn.
When the woman saw the mongoose's bloody lips, she
screamed for fear of what the creature had done to her
child, then crushed it with an iron pot. When she saw
the slain cobra by the baby's crib, she felt only regret.
