Cid is a recurring name in Final Fantasy, and Magic reflects this by not only featuring 15 different versions of the same card, but it also allows you to play as many copies of Cid as you want, no matter the format.
This is four blocks in two turns for five mana which is better than Squee at two blocks for six
For a product that usually retails around $30-$40, that might seem like a tough sell
The card flourishes in mono-green decks since Virtue of Strength only cares about Basic Lands
Feral Ghoul, meanwhile, gets stronger when other creatures you control die, and gives out rad counters to opponents when it goes to the grave
Bad Moon is subpar because you don't have enough black creatures and the majority of token creatures are not black, they're white or green especially since Prava only creates white creatures
