Glowing Winter

When Glowing Winter enters the battlefield, if
there is a card named Amber Autumn you own
in exile, draw two cards. Then, if you have a card
named Kayelthos, God of Seasons in your hand,
you may reveal it. Exile this card and shuffle the revealed card into your library.
At the beginning of your upkeep, exile Glowing
Winter and search your library for a card named
Dawning Spring. Put it onto the battlefield
and shuffle your library. Then draw a card.
