Strider

Vigilance, Haste, Reach.
Whenever Strider attacks, you may tap any
number of untappeds Florests you control: That number of targets creatures you control with
power less than Strider's power gains florestwalk
until the end of the turn. You can do the same for Plains and Mountains.
"But I am the real Strider, fortunately. I am Aragorn
son of Arathorn; and if by life or death I can save you,
I will."
