Guided by Nature is a great introduction to Commander or even Magic as a whole. It showcases a classic tribe with classic tribal synergies. These mechanics are easy to understand and powerful in their simplicity. I recommend tribal decks whenever I’m teaching the game to new players and still use the Kaldheim Commander deck, Elven Empire, to do so.
There was a time (if you can believe it) when Wizards couldn’t go one release without printing some elf tribal thing in a supplement somewhere, and Guided by Nature filled Magic’s yearly quota for elves in 2014. Led by Freyalise, Llanowar's Fury alongside Ezuri, Renegade Leader and Titania, Protector of Argoth for some reason, the deck revolves around (you guessed it) elf tribal!
This deck wants to play one elf on turn 1, two elves on turn 2, three on turn 3, and so on until you simply overwhelm your opponents. It includes some classic payoffs; Overwhelming Stampede, Overrun, and Beastmaster Ascension have all become venerated win conditions in mono-green decks.
You’ll never need creatures or mana since Freyalise, Llanowar's Fury can make a Llanowar Elves token every single turn. The consistency of that alone makes it very fun to play. Throw the regular elf tribal support package on top and you’re really cooking!
