Sandstone Oracle

The catch-up clause does all the balancing work here: it refills only against the opponent who has drawn furthest ahead, and only by the exact size of the gap. That makes it a self-correcting draw effect with no fixed ceiling and no fixed floor. Against a flooded control player hoarding answers it can draw five or six cards; against an empty-handed aggressor it draws nothing and leaves you a 4/4 flier. Pure card advantage stapled to a body usually has to be sized conservatively, because it can refuel whoever draws it regardless of standing, so designers cap the draw or charge a punishing rate. This design routes around that problem differently: it does not read the board or your life total, only hand size, so the ceiling scales with the disparity between your grip and the opponent you point it at. That makes it strongest when you are hellbent and someone across the table is sitting on a fistful of cards, and it does nothing when hands are even, whoever happens to be winning. At seven mana the effect lands slow enough that the body earns its keep as much as the trigger does, and the flier is there so the cast still feels worthwhile on a turn where the draw whiffs entirely. It belongs to the lineage of expensive artifact value-engines built for multiplayer tables, where "more cards in hand than you" has the most heads to compare against and the spread between the deepest grip and yours runs widest.
