Okay, here's how it works. First priority is Treeborn, so get that in the Grave any way you can, set it first turn on a naked field if u have to.
Next, get Substitoad in the Graveyard. You might be able to Special Summon Swap (by discarding Fishborg or Treeborn hopefully) first turn, then send Substitoad to the Graveyard with Foolish or Swap's effect.
Kinka Byo will summon Substitoad from the grave, and if all you can get is toad and Treeborn turn 1, then tribute them for Dupes to have a lock on until next turn. Remember with Kinka-byo to tribute Substitoad by its own effect last, otherwise it will be removed from play at the end of the turn when the Spirit Kinka-byo returns to the hand.
If you don't draw a Kinka, Salvage will get toad back to your hand for another round, and you can use the extra summon from Swap's effect after returning itself to your hand to summon it. I try to save Foolish to get a Fishborg in the Grave, or use One for One to get it on the field since its harder to get out of the deck than the Frogs and toad.
If your Dupe lock gets broken somehow, at least Dupe's effect gives you Frogs from your deck for thinning or recycles a Swap or Unifrog in the Grave.
Once you've got your lock out, you just hang in there until you have Fishborg in the Grave. Clear their back row with Unifrog, perhaps, thin your deck, maybe get a bit of draw with Avarice.
Once you've got Fishborg in the Grave with some cards you can discard in your hand, special summon Fishborg by discarding a card, use toad to Tribute another card for Des Frog, since all the material has to be Water Attribute for Fishborg.
Now you have lots of Synchro options. My first option is Fishborg + Des = Goyo. If you're not worried about thier backrow or retaliation next turn, then go for Brionac and clear the field, by all means.
You could clean up with Black Rose by Tributing the toad and Fishborg and Des if they have a heavy backfield or lots of face downs. Gungnir might be overkill at 7 stars, but it's secure enough if you dont have much to clean and you have in your hand a means to get toad back out from the Grave next turn.
Or if you've got a spare Dupe or 2 down as you should, go for the whole enchilada and bring out your Big 8 stars like Stardust or RDA (not the best choice if your lock is out, but it still works with Dupes in attack position). Mist isn't the most bang for your buck, but maybe you'd like to clear a few of your own monster zones while your at it and set up your grave for Avarice perhaps.
Ditching Dandy to summon Fishborg isn't often afforded by field space, since you already need to have a monster on the field for Fishborg's effect, but if it's Substitoad then you could be golden. I mostly use Dandy with Debris on an empty field to get a quick Stardust for extra insurance.
I've also got Diva's with Gillman (for the boost) in here too, since Fishborg is a bit finicky and it's an easy Catastor if you're screwed with an empty field and no other options. The main engine of this deck is Des Frog and Fishborg though.
So in summary, here's the simple Formula: Swap>Treeborn>Substitoad>Dupe Lock>Fishborg>Des Frog>Syncro (as usual Brionac is the Game changer)
Let's not minimize the role of the lone Uniforg in all this. He's a good last Summon when you tribute Substitoad if you've already managed to get your lock before your Battle Phase. He can avoid most stalls and break them, he can take out face down traps, since most people won't even bother to use a Prison on your Unifrog out of indifference or ignorance.
Also, the beatdown-ness of 3x Des Frogs (5700 ATK) on a clear field can't be underestimated, and if you got to a clear field with Brionac, that makes it an even 8000 for the round. So OTK is definitely within reach for this deck, though I've yet to pull it off.
All in all a reliable deck for me so far. It's contorted to play at times, and your time limit can be a problem in events, so practice. It's not so aggressive as the Frognarch's, so a little patience is required. You want to build so you usually have enough to get started right away first turn. Sangan, or Gold in a pinch, will pull anything you're missing if you can stall a few rounds.
Enjoy, and win some TP for VIP #1!
