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
Unfortunately, being one mana is a bit of a downside for a card like this because of its unfortunate interaction with Chalice of the Void, and cards like Diabolic Edict or any other two mana removal is probably a little more worthwhile
The card is structurally compromised and does not lie flat
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
This card is so ridiculously good, it dominated the game for years and actually changed the entire design philosophy the game is built around
