Stonecoil Serpent enters the battlefield with X +1/+1 counters on it.
Becomes a reprint in Challangerdecks 2021
2-of in Challenger Decks 2021
Joven Endless One has seen some Modern, Legacy and Vintage play it`s not the best Eldrazi but it`s a card that always has potential too see play due to being a free Eldrazi.
I think this one will indeed be more popular.
For commander i personal think this is a graet card
X/X creatures for X have not been popular in the past ("Endless One", "Wildcall").
Can 3 keyword abilities change that?
