Unlike most of the cards on this list (I have a playset from a different casual deck I built years ago) this is repeatable
This card, whose ability Vanessas Design enables players to force an opponent to discard a non-character card whenever they quest, has the potential to be very easy to play if put into a deck containing plenty of song cards
Control decks want to be able to slow down the game by handling early aggressive plays that might do critical damage prior to mass removal, they want to be able to do multiple things in a turn and they want to be able to snipe out tenacious creatures that might survive a mass removal spell
By casting it, players can deal 2 damage, and by casting another instant with 3 mana value or more, they can cast another, reaching the 4 damage required to give you a card draw during the end step
With Ojutai, the control player could then swing once they had counterspell mana up, and upon connecting once, the game was usually over, as they could chain counterspells, other interaction, or more Ojutai
One of my joys in Magic the past year years has been the design and execution of a cube made up only of Uncommon cards
