Equipment tutors have a place in that they are most often used to grab consistency pieces to help a deck get set up, and in the late game, they grab something to try and end the game
All of my five-color Commander decks are getting a copy of Urza
If they only have a few cards in hand, the choices of what to keep or discard are going to be much more difficult
Oh, yeah, and it also single-handedly reinvigorated Nykthos Ramp (aka Mono-Green Devotion) in Pioneer following the ban of Karn, the Great Creator as well
Those cards give you an equipment while this gives you an equipment and Magics only equipment trigger doubler, even if the equipment have to be on Cloud
its easy to get sucked in and spend way too much money on cards you never really needed anyway
