It's a blue legendary enchantment that, for two mana, allows you to look at the top card of your deck during every upkeep
Equipment as a theme has been one thoroughly explored in Magic's history, especially with preconstructed decks, so it's saying a lot that there's enough here to avoid inducing a collective groan when the word "Equipment" is mentioned
You opponent suffers when you give them a card like Steel Golem
Each player exiles all creature cards from his or her graveyard, then sacrifices all creatures he or she controls, then puts all cards he or she exiled this way onto the battlefield

The card is just disgusting
