This doesn't sound right at first thought, but when you realize that with more opponents there are more targets to choose from, in theory everything equals out
Add the fact that this enchantment is indestructible and can become a massive creature, and you have a strong card or even commander
The fundamental reason these cards exist is for playing with your friends for fun or to compete in tournaments
An aggro strategy that wants to get a lot of permanents on the battlefield to get the party rolling along
does not have a kind of Mana system, meaning if a card can be played it can be used right away
