>What did this SD need to be brought to a higher tier?
While the deck now has a 1 card combo and a better shot at extending past Speeder getting negated, the new revealed support more to them.
Looking at just the new support: Full speed needs a searchable E-tele or a monster that mentions Junk Warrior that can get an additional body on field, Anchor needs something that can send it to grave and Probably a tuner monster on field to climb with, and New Junk Warrior needs shit that can further set up the grave AND bring back Junk Synchron so you can actually make him as your plan B.
With all of that said as well, the deck will always struggle in the meta due to having no real plan into Maxx C/Fuwa.
