Feather, the Redeemed
Oracle Text
Flying
Whenever you cast an instant or sorcery spell that targets a creature you control, exile that card instead of putting it into your graveyard as it resolves. If you do return it to your hand at the beginning of the next end step.

Oh great, now I'm going to have to go correcting the Latin on interpretations of that song.
Also, yes, Boros Charm is a slam include in the deck. Double strike on your turn, hold up RW and pass turn so everyone at the table knows that you've got an answer ready for their shenanigans.
The greater value honestly comes from targeted cantrips. Drawing a card for a single colored mana is insane value. Like, you'd still play a card that was just literally "[W]: As an additional cost, target a creature you control. Draw a card" in this deck.
In commander, this plays a lot of the best stuff Zada, Hedron Grinder does (including Zada herself) and in standard I can't wait to do silly ***** with it in my Beamsplitter Mage deck.
