What type of deck do you want, elo or extended?
Well then imho go for cheap half decks so you can slowly phase out whatever it is you're using now without having to go all in immediately.
try aiming for the decent cheaper ones first - Carlito Massiv Raquel Kevlaer with Flinch Kyle Morgan Thorny Tobbie
that way you can try out their potential before going for the more expensive ones...
Try jakson harvey thomy tobbie bubbles chlora randal raquel (try using raquel as a finisher card more then an opener )
