Rhythm of the Wild is better than Domri, Anarch of Bolas as it gives a +1/+1 counter not +1/0 buff so it stays if Rhythm of the Wild is removed from the field. The counter works with proliferate and doesn't have to be triggered to make your creature spells uncounterable. It can't be attacked by creatures. It can give haste if you need that instead of a counter. It just gives you more options than Domri, Anarch of Bolas
