Yes, bitingbiting is better than fightingfighting, but it isn't so much better that I would build around a worse commander to take advantage of it
Both of these are worthy of being a three-mana spell on their own, but having them both on one card makes this a great card against a lot of different decks, and you can play it without worrying about what it is your opponent might be doing
It also has plenty of removal spells in Casualties of War, Putrefy, and Tear Asunder, if a particularly pesky Voltron player is threatening to block one of your many, many little critters
As the vast majority of preconstructed decks are built with the same general philosophy, its easy to see how it could develop its own player base that enjoys its play style
As such, unless Wizards announces that Secret Lairs will always come with a valuable bonus card, it's probably best to not expect any extra value and get a happy surprise if your drop happens comes with a bonus card on the level of Liliana, Teferi, or Jace
While Double Feature will certainly have lots of cards that synergize with each other, either from the same set or overlapping, taking the Chaos approach is a safe bet in this format
