Yusei stuff is what I wanted in terms of the theme (focus on Junk Warrior and Speed Warrior etc) BUT upon my first read of the cards they seem very very very VERY weak for modern day support.
Hopefully I'm just missing something obvious.

Outside of that...
>Burst Protocol
A few months ago I was posting about how i love the Rokket archetype and how I'd like it if they got some support which enabled them to be played in such a way that their unique playstyle could actually be used, aka the monsters being used as bullets/ammo which is something that just never happened, instead they were always just bodies to be linked off and that's about all.
My hope is that Burst Protocol gives us an incentive to end the turn on a boss monster with multiple Rokket monsters on the field that can be fired off to use their secondary destruction effects.

If the support turns out to be just more DLink fodder then meh, it is what it is, but hopefully not.
