- 25 February 2015Arashin Sovereign will be put on the top or bottom of that library only if it’s still in the graveyard when its ability resolves. If it leaves the graveyard before that point, it will stay in whatever zone it’s in, even if it’s returned to the graveyard before the ability resolves.
