Getting to dig for more permanents when it dies or getting to buff the team is an excellent tradeoff for losing a 5/4 with flying and vigilance
Vaporeon, Jolteon, Espeon, Leafeon, Glaceon, and Sylveon all have Special Illustration Rare versions in the set, and all of them are flipping for multiples over what similar rarity cards from other recent sets command

Fetch lands are kind of in their own little bubble since their use is to retrieve better lands, not to give you mana
You don't lose anything if your opponents choose to discard at the end of their turn, but it's better for you if they choose to keep their card and give you the option to drop a big Badnik onto the table
