Dragonlord Placidusax

Flying
Whenever a nontoken Dragon creature you
control would die, exile it instead with three time
counters on it. If it doesn't have Suspend, it gains
Suspend.
"The Dragonlord whose seat lies at the heart of the
storm beyond time is said to have been Elden Lord in
the age before the Erdtree. Once his god was fled, the
Lord continued to await its return."
