If youve had two lands enter the battlefield, giving you two triggers of this ability, you instead double the number of counters on that creature
When played, this card allows the player to exert up to 2 of their opponent's characters, meaning they won't be able to ready up at their next turn
Life is a resource in Magic
Although, remember, he's actually not a horror
Wilds Of Eldraine has powerful cards that exist in all colors, and in some cases colorless, that allow for any deck to splash them in with no problem
Also note that the Season and other +1/+1 counter effects will really break this Tribe since you can spend two mana to pull off one counter and then put two counters on the dork you targeted, plus the doubling when they entered the battlefield
