If you need a no-frills draw engine and don't care for anything else, Mind's Eye is a very efficient option
You can do it to all of them with Mycosynth Lattice or targeted effects from cards like Liquimetal Torque
Auora, Dreaming Guardian and Hercules, True Hero will help protect your high-lore characters and further control the board by making favorable trades, while Develop Your Brain and Beast's Mirror will help ensure that you can continue drawing more cards and consistently find your big characters
Out of them all, one card has an alternate art version that is only available in Surge Foil: Osgood, Operation Double
If you combine this bad boy with, oh we dont know, say a Dragon that gives things double strike and another one that can buff your Dragons, then you can wipe someone out in a single hit from just this one Creature
