Love Maze

Found Love - Whenever a creature enters the
battlefield under your control, choose another loverless creature on the battlefield at random.
The chosen creature and that creature are now
lovers. At the beginning of your upkeep, if that creature has no lover, repeat this process.
Creatures with lovers with the same controller get
+3/+3 and gain Trample.
Creatures with lovers with different controllers
get -3/-3 and lose all abilities.
