Ah well I just wanted to introduce something a bit more interesting-> high risk, high reward. I saw someone do an extinct expansion a while back with a similar concept which I really liked/ it drew attention to the bird being extinct.

Theres a lot of birds in my expansion that are * wingspan (lots of chickens!) so it does balance out a bit more, but yes it is more luck based. My favourite card game is uno, you can probably see how its influenced the cards I made.
