The "Market Price" indicator gives you a reference point, and you can almost always find the card you want at or slightly below market
And although the opening fortnights craziness is beginning to calm down, its still a surprisingly pricy collection
Emet-Selch gives you the same effect on a permanent basis, provided youre willing to put in the work
I was very happy to find it even includes some cards Ive long wanted but didnt yet have namely Winnie the Pooh - Hunny Wizard
Archmages Charm is extremely pushed, a solid permission spell, a good way to build card advantage for hitting land drops, and a fantastic tool against Deaths Shadow, Wild Nacatl, Goblin Guide, Pyxis of Pandemonium, Champion of the Parish, Aether Vial, Delver of Secrets, Hardened Scales, Amulet of Vigor, Benthic Biomancer, Glistener Elf, Noble Hierarch, Viscera Seer, and sometimes even Hexdrinker (just to mention a few)
I think for a deck that embraces flooding the field with characters and bouncing would-be-banished characters back to your hand, the cards that let you heal (which are almost never useful in any trading card game) are wasted space here
