Flying
Whenever you draw a card, Niv-Mizzet deals 1 damage to any target.
Whenever a player casts an instant or sorcery spell, you draw a card.
Resolve Niv-Mizzet, Parun and turn every spell cast at the table into card draw, then convert that draw into pings that grind down opponents or fire off a lethal burst. You build a spellslinger engine of cantrips and rituals, protect Niv, and either ping each opponent to death or assemble a draw-trigger loop. Until then, you use cheap interaction and card advantage to stay ahead.
Add fast mana and protection like Mana Drain, Mana Crypt, Dramatic Reversal plus Isochron Scepter, and Veil of Summer or Heroic Intervention to shield Niv. Tighten the spell base to high-impact cantrips and tutors (Mystical Tutor, Merchant Scroll) to find Curiosity-style combo pieces faster, and include Underworld Breach or Aetherflux Reservoir lines for redundant kills. Prioritize cheap interaction so you survive to deploy and loop your commander.
