Curiosity + Niv-Mizzet, Parun

Overview
When Curiosity is attached to Niv‑Mizzet, Parun and Curiosity's controller is also Niv‑Mizzet's controller, an instance of Curiosity triggering (when Niv‑Mizzet deals damage to an opponent) can let that player draw a card, and each card drawn triggers Niv‑Mizzet's "Whenever you draw a card" ability causing Niv‑Mizzet to deal 1 damage to any target, which can retrigger Curiosity if that damage is dealt to an opponent, creating a repeatable chain of triggered abilities .
Step 1
Curiosity is an Aura attached to Niv‑Mizzet, Parun on the battlefield; Auras and what they can enchant are governed by the enchant rules .
Step 2
When Niv‑Mizzet deals damage to an opponent, that event meets Curiosity's trigger condition and Curiosity's triggered ability is created ("Whenever enchanted creature deals damage to an opponent, you may draw a card") .
Step 3
That Curiosity triggered ability goes on the stack and, when it resolves, Curiosity's controller may draw a card as the ability's effect resolves .
Step 4
If the player who draws the card is also the controller of Niv‑Mizzet, each card drawn causes Niv‑Mizzet's triggered ability ("Whenever you draw a card, Niv‑Mizzet deals 1 damage to any target") to trigger and be put on the stack .
Step 5
When each of those Niv‑Mizzet draw-triggered abilities resolves it deals 1 damage to its chosen target; if that target is an opponent, Curiosity will see Niv‑Mizzet deal damage to an opponent and trigger again, producing another optional draw .
Step 6
Because Curiosity's draw is optional ("you may draw a card"), the controller can stop the loop at any time by choosing not to draw; alternatively, Niv‑Mizzet can target something other than an opponent to avoid retriggering Curiosity .
Step 7
If Curiosity's controller is different from Niv‑Mizzet's controller, a draw caused by Curiosity is a draw by Curiosity's controller and does not trigger Niv‑Mizzet's "Whenever you draw a card" ability for Niv's controller (see Ruling [2011-09-22]).
Step 8
Curiosity does not trigger when the enchanted creature deals damage to a planeswalker or a battle, only when it deals damage to a player (see Ruling [2023-09-01]).
Resolution
If Curiosity is enchanting Niv‑Mizzet and both permanents are controlled by the same player, each time Niv‑Mizzet deals damage to an opponent Curiosity's triggered ability may let that player draw a card; each draw creates a triggered ability from Niv‑Mizzet that deals 1 damage to any target, and if that damage is dealt to an opponent Curiosity triggers again. The draws are optional because Curiosity's ability uses "may," so the controller can stop the chain by declining to draw . If Curiosity's controller is not the controller of Niv‑Mizzet, a draw caused by Curiosity does not count as "you" drawing a card for Niv‑Mizzet, so Niv‑Mizzet's draw-trigger will not trigger from that draw (see Ruling [2011-09-22]). Also, Curiosity only triggers when the enchanted creature deals damage to a player (not a planeswalker or a battle) as noted in Ruling [2023-09-01].
