Plasma Deck. Not necessarily because it's the easiest but just because it's the only deck that completely changes how you play. I love the idea of having to maximize chips and I often use jokers I usually wouldn't before.
It "balances" your score so that chips and mult will be equal. If you have 40 chips and 10 mult, add them together and divide by two. Now you have 25 chips and 25 mult.
