Rielle, the Everwise Rielle, the Everwise encourages you to discard cards to set up explosive turns with its card draw ability
Its effect is kind of m'eh, though, just buffing Gus depending on the amount of wins and losses you have with a specific opponent, which is sure out-of-the-box but not as zany as some of the other effects on this set
One such mechanic was connive, which nets you a loot (draw, then discard) with a bonus +1/+1 counter if you discard a nonland card
Any creature you control that couldn't be targeted by the original spell (due to shroud, protection abilities, targeting restrictions, or any other reason) is just ignored by Zada's ability
This thing was so powerful it was run in Vintage decks among many other formats
If you somehow cast this spell when it's not a main phase, the second ability still takes effect, but there are no additional combat phases this turn
