Due to the enhancement of the card pool, there are various merits of being a "Gaia the Fierce Knight" monster, such as being a fusion material with a specified name, but the highest level monster with a total attack and defense value of 4400 and level 7 is the first term standard

shuffle that face-up Effect Monster into the Deck, then your opponent can Special Summon 1 monster with the same name from their Extra Deck
You may not need to increase your land count by much if you add a bunch of ramp spells and rocks
This is doubly effective if those artifacts are also mana rocks, meaning its easy to get this commander out much sooner than one might expect for 8 mana
