This was one of those cards that a lot of decks were on the edge of playing, either because they couldn't quite get threshold reliably or they didn't want to splash one of the colors, inviting them to play a high-risk but high-reward game with their mana bases that both cost them games and won them games they had little right to win

Even ignoring how Tinker can cheat powerful artifact creatures into play, theres any number of other ultra-powerful artifacts that combo up effectively with it
I prefer White Sun's Twilight as the Phyrexian Mites provide a unique axis of pressure, but a deck thats interested in one will likely run the other
Because Necrodominance exiles any card that would go to the graveyard, it causes every single one of your spells to cantrip
If they dont have a blocker, adding menace to your own attacker is almost as good
