It depends on your cube's power level and the types of cards/decks that tend to be popular among your group. I included this Niv in my lower power cube and he has overall been less powerful than he tended to be in standard at times, but exciting and fun enough that a few of my regulars have enjoying playing him in their Izzet decks. "Cube Blue Red" tends to be a popular archetype here, though.
