Beyond card advantage and mana advantage, I think most of the other staples are concentrated most in Black with stuff like Demonic Tutor and Reanimate, and Blue has countermagic like Mana Drain and also a bunch of great theft cards like Bribery
There are only 3 other cards that reference exploring, but two of the payoffs -- Nicanzil, Current Conductor and Topography Tracker -- are both incredible, definitely worth it if Hakbal is your commander but the first cuts if you swap commanders
Last but not least, there are cards that are clues without being tokens , like Scene of the Crime (which is also a land), Tangletrove Kelp (which is also a creature), or Five Hundred Year Diary
You can go all out and play Impact Tremours - the mini Purphorus
Each pack contains 14 Magic cards and 1 token/advertising card or art card
