The legendary animals take 3 times longer, but they also have 3 times increased food per harvest!

ahaha You are absolutely right I made a mistake and need to correct the information in the post, reading the whitepaper I had read the price column instead of food.

So the only real advantage of legendary cards is their market price ... at this point I think I'll try to sell them even if the time savings is still a good price to pay ...

For the Dog I for the moment have decided not to take it and I don't know if I will because at the moment its production/cost is not very advantageous compared to using seeds and gardens but I think the dog will be very useful when the breeding function is introduced.
Maybe I will take some future Pets
thanks for your useful comment @nelthari
