Niv-Mizzet, Parun

Players can cast spells and activate abilities after Niv-Mizzet's second triggered ability resolves but before the spell that caused it to trigger does. Notably, the card you draw may be able to counter that spell.

If a spell or ability causes you to put cards into your hand without specifically using the word "draw," Niv-Mizzet's first triggered ability won't trigger.

If an effect instructs you to draw multiple cards, Niv-Mizzet's first triggered ability triggers that many times. You choose targets for those abilities after you've drawn all of the cards.
