Maester of Winterfell

Whenever an artifact enters the battlefield under
your control, you may put a land card from your
hand onto the battlefield.
"Oh, to be sure, there is much we do not understand.
The years pass and what does any man see of life but
a few winters? We look at mountains and call them
eternal, and so they seem ... but in the course of time,
mountains rise and fall, rivers change their courses,
and great cities sink beneath the sea. Even gods die,
we think. Everything changes."
