Alexos, Student of History

When Alexos enters the battlefield, or during your upkeep, each player reveals the top card
of their library until they reveal a non-land
card. If you revealed the card with the oldest copyright date, put a lore counter on Alexos. Put the revealed cards on the bottom of their owner's libraries in any order.

{t}: Draw X cards, each opponent loses X life, and you gain X life, where X is the number of lore counters on Alexos.
