If a spell or ability an opponent controls causes you to discard Loxodon Smiter, put it onto the battlefield instead of putting it into your graveyard.
If you discard Loxodon Smiter and put it onto the battlefield, you've still discarded a card. Abilities that trigger when you discard a card (such as the one from Liliana's Caress) will still trigger.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
