There aren't many two mana tutors that don't cost a card to use and offer this kind of flexibility, but most creatures are valuable because they are efficient rather than because they are the right tool for the job
Locations can always be challenged, and you dont need to wait for them to be exerted as they cant
In the formats where Tinker is legal, its easy to play it on turn 1 and offers explosive potential, whether you're fetching a Bolas's Citadel or Blightsteel Colossus
It can even answer those for 7 mana, which makes this supremely efficient and flexible
Tons of Ux Tempo, Control and Combo decks with plenty of non-creature spells which dont like to see an early Esper Sentinel on the board
