As for which one wins
There are also six cards that have been completely removed, either because of them using ante (a mechanic that has long been abandoned due to its close proximity to gambling) or because of offensive content
Arasta of the Endless Web Arasta of the Endless Web is a fine card, but its rather lacking in the commander department, in large part because the best spider payoffs are black cards like Rotwidow Pack and Shelob, Child of Ungoliant
Earthcraft is the best source of mana to fuel a number of infinite combos involving Doubling Season, Cathars Crusade, The Meathook Massacre, and Corpse Knight, among others, but these cards only scratch the surface of your combo potential with this commander, so if thats your preferred style of play, the linked primer above is going to be your best starting point for deck construction
It can also be used in a few different ways: you can swap out your Stage 1 cards for Rare Candy cards instead, freeing up room for other key cards, or you can include it alongside those cards to essentially give you 3 or 4 cards that get you to your Stage 2 Pokmon, massively increasing the consistency of any deck that plays Stage 2s
