Race Race

Populous creatures get +1/+0; non-Populous creatures get +0/+1.

At the beginning of your upkeep, if an opponent controls more Populous creatures than you, reveal cards from the top of your library until you reveal a creature card; put the revealed creature into play under your control, and the other cards revealed in this way into your graveyard.

Sacrifice Race Race: Each player draws 2 cards.

(Populous: of the most common or tied for most common creature type(s) in play.)
