Since I'm sticking to the script of being nega-MTGO Vintage, the March update has goozled me once again by having picked up Greasewrench Goblin and Ivora, Insatiable Heir as ways to support discard shenanigans and instant-speed trickery.
Also Up the Beanstalk has at long last finally snuck its way into MTGO Vintage so a lot of the 5+ support that I've been stockpiling can probably go since that's kind of DOA without beans. It's a shame too because Beans was a lot of fun while it lasted. It's definitely a mechanic that works surprisingly well at a variety of power levels.
