Bought these for my wife for Christmas who plays a druid. Haven't used them yet but i think they will be great. So much useful info and hopefully will save a lot of time. Cards also seems high quality and feel sturdy.
Only small issue would love to have a few more higher CR creatures for the Moon Druid. But since these are from the open source material its understandable that there isn't.
Still great enough for 5 star in my opinion
