Elesi, Heaven's Majesty

Flash, flying, vigilance
Whenever Elesi enters or leaves the battlefield,
tap all permanents your opponents control and
untap all permanents you control. Your
opponents skip their next beginning phase.
(The beginning phase includes the untap, upkeep, and
draw steps.)
If this card leaves the battlefield, or is put into
your graveyard or exile from anywhere, exile
it with a binding counter on it instead.
