Flying, vigilance, haste
Whenever a player attacks with three or more creatures, you draw a card.
Whenever a player attacks with five or more creatures, Aurelia, the Law Above deals 3 damage to each of your opponents and you gain 3 life.
For both triggered abilities, it doesn't matter what happens to the attacking creatures in response. As long as a player attacked with at least the appropriate number of creatures, the effects of Aurelia's triggered abilities will still occur.
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.
