The Next Regionals - Much More Testing

My playtesting is increasing by the day. At work, I have nothing better to do than to play cards with myself. These are the current updates:

Mermails - After much discussion with peers, and testing, it seems I will be playing Mono-Mermails if I decide to take Mermails. I finally did get an Abyssleed, which is quite helpful, although I haven't actively tested it. I'm currently focusing on making the deck more explosive, but at the same time, not losing to Shock Master. Also, I don't have 3 Megalo, and I'm not 100% confident with 2 Megalo in this deck, for a Regionals. The extra deck is quite tight, and that will need some serious work.

Fire Fists - A couple days ago, I was pretty hot with this deck (no pun intended).. I'm pretty sure I've mastered at least 90% of this deck's combos. I've found the variant I would play, and the extra deck isn't questionable. I just need to finalize the deck list, and then I might take this deck to Regionals.

Dino-Rabbit - I slightly changed the variant for this deck. I've been testing Cardcar "D", in order to speed up the deck. After I resolve this card, I either lose on my opponent's next turn, or have a significantly higher chance of winning if I stay alive. Also, against Mermails and Fire Fists, there is a direct correlation between drawing Macro and winning, if Macro stays up the entire game.

Before I dive into the other possible decks, I feel the need to state the following about the above three decks: I've tested all 3 decks against each other, and they all have a 50% win ratio against each other. This isn't making my decision easier, however, I will probably end up taking one of those decks in the end.

Dark Worlds - This deck is still an option, because it is too broken. I can honestly say after watching people at Locals playing Dark World since the structure deck was released, I play the deck a lot different, and I'm better by default. There isn't a lot of room for complicated thinking and skill in this deck, but when it is an option, that's usually when I have game. I've also edited my variant once again, and this variant focuses on withstanding Macro.

Prophecy - A lot of people will probably wonder why I'm deciding to consider this deck. My reasoning is simple: A lot of people will not thoroughly prepare for this deck until Divine Judgment is released... That's really it. When the card is released, there will be an increase of cards to counter it. Right now, not a lot of people care. With Mermails and Fire Fists running rampant, Prophecy has a good shot since those decks bear very few counters to this deck, thus making it a decent choice.

That's it for now. My next post will likely entail side-deck discussion and whatnot. Like usual, please share any advice or feedback.
