The card is structurally compromised and does not lie flat
The equip ability on its own, without outside help from cards like Leonin Shikari, cannot be activated at instant speed, so if you play an Artificers Hex on an equipment thats already attached to a creature, they will not be able to remove that equipment before they are in their main phase, guaranteeing you a dead creature
a highly-graded card is void of scuffing, creasing, scratches, and any sort of blemishes immediately apparent on the front or back of the card
That said, its power level is quite high, and like Mana Leak or Lightning Bolt being in Standard, it will be a defining component of the game during its entire life in the format
It seemed solid to me
This same synergy exists with Sickening Shoal
