How many factions are there?

In terms of parameters, these are quite similar creatures. They have the same HP, similar damage, and attack and defense stats... But what distinguishes them, besides their appearance, is the presence of specific abilities. All creatures have their own, including upgraded versions. You can't just say that stalkers and aces are the same. They differ in appearance and abilities, just like the other upgrades in the game. This is what I mean: there are so many new creatures, but gamers still want more. The same goes for the factions. Once you play, the 42 new creatures (if there are two factions) will become old creatures. Currently, there are 168 creatures in the game, not counting neutral ones. Do you think these 42 will change anything?
