The Constitution

Will of the council — When The Constitution
enters the battlefield, starting with you, each
player votes for Equality, Checks and Balances,
or Tranquility. The Constitution gains each
ability with the most votes or tied for the most
votes.
Equality - Players can't play more than one land
or draw more than one card each turn.
Checks and Balances - Players can't search
libraries.
Tranquility - Cards in all graveyards gain shroud.
