Sarvaerys, Lord of Amber

{w}{r}{g}, Reveal Sarvaerys, Lord of Amber from
your hand: Put another creature card from your
hand onto the battlefield with an amber counter
on it. Creatures with amber counters on them
can't attack or block, and their activated abilities
can't be activated.
At the beginning of your upkeep, gain life equal
to three times the number of amber counters on
permanents you control. Then, you may remove
an amber counter from target permanent.
