Get rid of the Rescue - they suck in half decks. Replace it with another atk manip clan, or even a power manip. Also, you might want to get staples like Tremorh and Qubik. Although i don't play Junkz, i might suggest Junkz/Piranas, as they are both centred around pillz manip
Its not so much they are a horrible half deck they can be +6 or +9 its just they work best mono. Its most unorthodox to see a Rescue half deck.
value to value and one of those more popular and thought to be stronger combos out there would be Uppers with Junkz you could use HermanJodyHefty and Harold and put Dreen to Flanagan at the very least IMO
