Hands down, this is one of my favourite decks and I have never been so hyped for some cards to be released. (Awaiting Castor and Thunderbird).
Basically, Verz (Evilswarm in TCG) are infected versions of other YGO cards.
This version of the deck, (will have pure up at some point), utilizes the Macro Rabbit build that is topping everywhere and infects it. (Click the names if you don't know what they do).
x2 Evilswarm Ophion
x1 Evilswarm Bahamut
x1 Evilswarm Ouroboros
x2 Evolzar Laggia
x1 Evolzar Dolkka
x1 Number 16: Shock Master
x1 Makestroke the Symphony Djinn
x1 Gagaga Cowboy
x1 Photon Papilloperative
x1 Number 50: Blackship of Corn
x1 Leviair the Sea Dragon
-2 Fiendish Chain
+2 Torrential Tribute
The deck works in the same way as Macro Rabbit, but with the support of broken Verz monsters. Ophion stops both players SS'ing Level 5 or higher monsters. Bahamut is change of heart on legs and you have the most broken support card in the game, Pandemic Pandemic Infestation, which makes all (Steel/Evil)Lswarm monsters unaffected by Spell and Trap.
The deck is simply nuts. Evilswarms have amazing consistency in the pure and add a amazing element of it to Macro Rabbit. The amount of times I have gone first turn Ophion outside of Rabbit is nuts.
I really like the decktype personally. A few comments...
Is triple Lance necessary? Why not go to triple Macro? Fiendish Chain is kinda bad this format, so consider running something else. You should definitely run more powerful defensive Traps like Torrential Tribute or Solemn Warning in this deck, considering you have space to even run D-Prison. : o
Also I really like Spirit Reaper in this kind of deck. Try it! Conversely I have never tried Guaiba but it is probably not terrible.
