If an effect instructs you to draw cards and then discard cards, you can't take actions in between. For example, if you have no cards in hand and cast Faithless Looting, you can't activate Seismic Assault's ability between the time you draw two cards and discard those two cards.
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.
