It is Jokers/Fire and is a basic deck for beginners. Many of its art features characters from various other CoroCoro things. And Baron even features a Kirby!
This is another DMSD deck, this time based on Boltz and his Beat Jockeys.
As seen on Bad Brand Limited (as well as the promo Bad Brand First), they both feature the following ability:
B·A·D 2 （You may reduce this creatures summon cost by 2. If you do, destroy this creature at the end of the turn.）
So you have the option to make them cheaper, but they'll die at the end. They each have speed attacker though.
