Hodohr, God of Friendship

Victory — Your teammate wins.
Defeat — You or your teammate are eliminated.
When a player Announces, Announce (Turn
this card face up to reveal your role.). If you do,
starting with the player who triggered this ability,
that player may top the high bid. The bidding
ends if the high bid stands. The high biddes loses
life equal to the high bid and sacrifices a quarter
of the lands they control rounded up. Then that
player becomes your teammate.
