Witching Hour (Game Mechanic)

Witching Hour: If the total number of cards in players hands, permanents on the battlefield, and
cards in graveyards is 28 or more, it is the
Witching Hour
This mechanic is meant to replace the somewhat clunky Day/Night mechanic thematically. The Witching Hour is meant to give late game buffs to certain cards, accelerating the game. Of course
one can manipulate the game state by either using cantrips to make it 'night' or exiling to keep it 'day'
