Just thought it would be cool to have some sort of reward or buff (cost reduction, more damage or something like that) for X type of creature if your deck is composed of at least X amount of that type of creature. For example, a deck with only forestkin, demons, humans, beasts, elementals, constructs and so on. It could work on a cardbase-wide basis since for example there are no tier 1 constructs and there arent as many as there are demons, and humans got a lot of cards to play around with. If i had to give a hard example. There are 7 forestkin units: 2 Treespirits, Spikeroot, Thornbark, Razorleaf, Spore Launcher and Grimvine, so having 6 of them (1 of each creature) would get those forestkin cards a 10% cost reduction, damage increase or damage reduction buff. Something along those lines. In the example i did use a creature type that doesn't really have as much variety but other types like demons, beasts and humans got a LOT of creatures, so with those it could work with a lower amount from the total. The idea is to build a deck around that type of creature specifically, it would be obviously suboptimal otherwise but also challenging and thematic. If the buff idea is too hard to balance or hard to code since it would need to detect all the cards and i got no idea how that could work, then another idea would be to turn it into an achievement. I know this can be somewhat done since there is an achievement for dragons already so it would be just a matter of changing the type. The achievement could involve playing a really large number of creatures of that type, with a little restriction to avoid farms on easy maps where you'd just sit there and spam them forever. And the reward could be a booster pack of the creature's element or maybe even a title, for example for Forestkin it could be "The Green Plague", for humans it could be "Scion of Lyr", for beasts it could be "Apex Predator" and so on.
