創造の魔道士、ニッサ

While resolving Nissa’s last ability, all creatures and lands put onto the battlefield this way enter at the same time. If any have triggered abilities that trigger on something else entering the battlefield, they’ll see each other.

You can activate Nissa’s first ability with fewer than four targets. For example, you could target one creature and two lands, or no creatures and two lands. You could even choose no targets at all.
