I find it... err... kinda 'cheesy' and dumb when people say they 'needed' to spend real cash to build this deck.
Is that some kind of joke? me and many guys I know have built this deck completely for free, (it wasn't difficult at all to begin with) since the gem drops and rewards have increased during the last months.
The only cheesy decks that require cash are stuff like Geartown Turbo which mandates you buy it three times to get the materials you need. All other pack decks can be acquired via gems. Considering you can get 200 - 300 gems by leveling a character once, its super easy to grind once you have achieved some amount of momentum
Not require cash? This deck is played with Kaibab Corp skill and prismatic/glossy Core now, do you know how many packs needed to get it? It is whale deck
