My friend, teammate, and fellow expert Legacy theorist Capt4in (@cattribal on Twitter) asked me today why Tinker isn't legal if Show and Tell isn't bannably overpowered. So what would you do in Legacy with Tinker? Our thesis is that the usual Vintage target, Blighsteel Colossus, wouldn't be as good in Legacy due to the preponderance of relevant removal and that moreover making a Griselbrand for the same amount of mana is a substantially higher-power play anyway. Memory Jar is another favourite target in Vintage but that card is banned in Legacy. The best we could come up with is setting up a Mindslaver lock or getting Sundering Titan. What would you do with Tinker in Legacy?
