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.

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.
+2: Untap up to two target creatures and up to two target lands.
−3: Target creature gets +5/+5 until end of turn.
−10: Look at the top ten cards of your library. You may put any number of creature and/or land cards from among them onto the battlefield. Put the rest on the bottom of your library in a random order.
