Ecosfera: My Favorite Mechanism

About Ecosfera, from BoardGameGeek:

Ecosfera is a cooperative deck-building game with different levels of difficulty where we must restore nature before it's too late. Water, time, earth, air and sun / these are the elements that you will use to get cards from the plant and the fungi kingdom. But be aware! there are also natural disaster cards. Luckily we have extra abilities such as changing cards, extra cards and passing a card to another player With the right combination of plant cards you will get animals and with the right combination of animals, you will achieve biome tiles and hopefully you will rewild the world together. -description from the publisher
