Creatures you control have vigilance.
+1: You gain 3 life.
−2: Put a +1/+1 counter on each creature you control and a loyalty counter on each other planeswalker you control.
If Ajani is somehow a creature as his last ability resolves, he’ll get a +1/+1 counter.

If a planeswalker you control is also a creature (most likely because it’s Gideon), that planeswalker receives both a +1/+1 counter and a loyalty counter as Ajani’s last ability resolves.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
