Actually, its really easy to understand. The deck is basicly anti-meta and counters alot of plays that the bigger decks (Tier 1 and 2) play. The key to this deck though is that it has an engine that its viable and not dead even if you aren't playing against a Tier 1-2 deck, which consist of recycling Neos Alius through chainable spell/traps that net advange with Gemini Spark and Hero Blast or through big buffy fusions like The Shining, which forces your opponent to play removal on.
The problem with this deck though is that it can crap out against Tier 3 or lower decks, which is why the side is possible the most important aspect of the deck; to be flexible as possible. There was a reason I sided Skill Drain and Barbaros out against you because it didn't have that much of an use, since you played a crapload of backrow removal (MST/Heavy/Sparks) and it was more heavily based on the grave and I sided in MSTs, Smashings and snowman eaters instead.
To play this deck, you have to know your match-ups you're going to get and adjust yourself to it, which some people also playing Hero Beat dont seem to understand.
And TBH I really hate Bubblebeat because I found it to be extremely susceptible to bad hands and removal. :S
