Creatures (22) 2 Llanowar Elves 2 Elvish Mystic 2 Tireless Tracker 4 Hydroid Krasis 4 Gilded Goose 4 Wicked Wolf 4 Brazen Borrower Planeswalkers (8) Lands (24) Spells (6) Yup, this is basically a Standard deck
Otherwise, its controller may search their library for a basic land card, put it onto the battlefield tapped, then shuffle. In essence, this is a ramp spell that can also be used to destroy problematic artifacts or enchantments, and thats a really interesting bit of design, and well worth picking up for your decks
