Trailer Park

When you become the target of a player's unwarranted aggression you may have that player discard 1 card and you draw 1 card.
{r}, Discard a land card: Choose a card from each player's library at random. Each
player puts that card in their graveyard.
{w}, Discard a non-land card: Choose a card from each player's deck list at random. Cards with the chosen names cannot be played until after your next upkeep.
