Curiosity + Niv-Mizzet, the Firemind
Overview
If Curiosity is enchanting Niv‑Mizzet, the Firemind and the same player controls both, tapping Niv‑Mizzet for its 
: Draw a card ability starts a loop: drawing triggers Niv‑Mizzet ("Whenever you draw a card, Niv‑Mizzet deals 1 damage to any target"), dealing 1 damage to an opponent triggers Curiosity ("Whenever enchanted creature deals damage to an opponent, you may draw a card"), and that draw triggers Niv‑Mizzet again — continuing until someone stops it (for example by choosing not to draw) or the loop is interrupted by game-ending or other state-based effects; see Ruling [2018-03-16] and Ruling [2011-09-22].
: Draw a card ability starts a loop: drawing triggers Niv‑Mizzet ("Whenever you draw a card, Niv‑Mizzet deals 1 damage to any target"), dealing 1 damage to an opponent triggers Curiosity ("Whenever enchanted creature deals damage to an opponent, you may draw a card"), and that draw triggers Niv‑Mizzet again — continuing until someone stops it (for example by choosing not to draw) or the loop is interrupted by game-ending or other state-based effects; see Ruling [2018-03-16] and Ruling [2011-09-22].Step 1
Curiosity is attached to Niv‑Mizzet, the Firemind and is a legal attachment on the battlefield .
Step 2
You activate Niv‑Mizzet’s : Draw a card ability; when that ability resolves you draw a card.
: Draw a card ability; when that ability resolves you draw a card.Step 3
When you draw a card, Niv‑Mizzet’s triggered ability "Whenever you draw a card, Niv‑Mizzet deals 1 damage to any target" triggers and is put on the stack (this is the ordinary triggered-ability sequence).
Step 4
When that Niv‑Mizzet trigger resolves it deals 1 damage to the chosen target. If the chosen target is an opponent (a player), that damage causes Curiosity’s trigger "Whenever enchanted creature deals damage to an opponent, you may draw a card" to trigger (Curiosity does not trigger for planeswalkers or battles — Ruling [2023-09-01]).
Step 5
When Curiosity’s trigger resolves, its controller may choose to draw a card (it is optional). If they draw, Niv‑Mizzet’s "Whenever you draw a card..." triggers again, and the cycle repeats; if they decline, the loop stops. This repeating behavior is described in Ruling [2018-03-16].
Step 6
The loop continues until someone chooses not to draw, the relevant players lose or the game otherwise ends (for example lethal life loss leading to a loss , or an attempted draw from an empty library causing a loss ).
Resolution
If the same player controls both Curiosity and Niv‑Mizzet, tapping Niv‑Mizzet to draw can produce a repeating draw → Niv trigger → damage → Curiosity trigger → draw loop that continues until interrupted. The loop can be stopped by declining Curiosity’s "may" draw, by choosing targets that don’t cause Curiosity to trigger (for example, dealing damage to a planeswalker — Curiosity doesn’t trigger for planeswalkers — Ruling [2023-09-01]), by different players being the relevant "you" (Ruling [2011-09-22]), or by a game-ending/state-based event such as a player dropping to 0 life and losing the game or a player attempting to draw from an empty library ; see Ruling [2018-03-16].
