Synapse Sliver solves that problem by giving every sliver the potential to draw cards if they deal combat damage to a player
Flash makes it versatile against all sorts of stuff, including notorious card drawing permanents, planeswalkers, cascade, etc
Another rare choice, Lim-Dul's Paladin is a wonky creature from the Alliances block with a few paragraphs of text that basically amount to it either being a 6/6 with trample, or just 4 lost life
The handful of smaller mechanics like meld, devotion, and hideaway arent very impactful to the draft set, but they are nice inclusions of Final Fantasy flavor
That holds doubly true now that certain Lorcana cards are being auctioned for huge amounts of money
Decks that focus on untapping their permanents are different , though
