When Linas's Throne enters the battlefield exile
all other permanents and put a Linas counter on
them.
When Linas's Throne leaves the battle return
all cards in exile with a Linas counter on them to battlefield under their owner's control.
{p/b}{p/c}{p/g}{p/r}{p/u}{p/w}, Sacrifice Linas's Throne: You take
the initiative. Venture into the dungeon. If it's
neither day nor night, it becomes day. You
become the monarch. The ring tempts you.
