It must be difficult to keep track of creatures A-Z since new ones come out every week or smth XD. Also a tip once your further on in the challenge, if you're low on health as a flying creature swoop in and attack your target, then return to somewhere higher to gain health. Another tip is that if your being chased by a big flyer, like a raiquazok, try get up high places so it will keep on flying, and since huge flyers use a lot of stamina in the air they would just start gliding. Which is useful for you. I just realised ive typed more than I needed to so ill stop now XD
I like ur concept, but as the other comment says, its gonna be ah ell of a ride to keep track of each creature, i dunno if u'd like me to propose this idea but: i encourage you to stick with creature that are seen aa bad or are simply forgotten and unused
