The decklist I was showing at the beginning was on GUdecks.com (link for your reference) https://gudecks.com/decks/GU_1_5_CATCATCArCArCAtCAtCAuCAuCBxCBxCCOCCOCDLCDLHAEHAEHAFHAFIATIATICHICHIDFIDFIDKIDKIDMIDMIDNIDN?godPowers=100121&creator=[TOXIC]%20FakeMews&userId=147667&archetype=Big%20Beasts%20Nature

Another Round is a war-class specific card so it is not legal in a nature deck. You can only play Another Round in your war decks.

Yeah I also agree that learning on what points to focus is important for me in the content creation aspect. The things I worry about in certain lists are likely not concerns or even thoughts for a lot of people. But explaining the process is always important over time the more videos I make I should improve (in theory).
