FlyingWhen Niv-Mizzet Reborn enters the battlefield, reveal the top ten cards of your library. For each color pair, choose a card that's exactly those colors from among them. Put the chosen cards into your hand and the rest on the bottom of your library in a random order.
Rulings:
- 5/3/2019 A “color pair” is exactly two colors. There are ten color pairs in Magic: white-blue, white-black, blue-black, blue-red, black-red, black-green, red-green, red-white, green-white, and green-blue.
- 5/3/2019 If the top ten cards of your library don’t contain all ten color pairs, you choose as many cards as you can and put those cards into your hand.
