Tezzeret's Touch

Commander is where Tezzeret's Touch does its best work — artifact-heavy commanders generate enough cheap targets that the enchantment rarely sits idle, and the return-to-hand clause creates a resilience loop that grinds opponents down over a long game. In Modern and Legacy, the three-mana investment competes against faster, more redundant threats, so Tezzeret's Touch mostly stays on the shelf in those formats despite being legal. Pioneer offers a slightly slower field where it's theoretically castable, but the artifact synergy density in that format doesn't justify the slot. Oathbreaker, like Commander, rewards the card in Tezzeret-led builds where artifact tokens and utility pieces are abundant.
