There are note worthy cards that make both decks run well.
Ceremonial Mirror, Level 8/6 Rituals and Gishki Shadow are the main focus of the deck. They provide the deck with recycle, beatdown, and search tactics that pretty much turn the tide for them or set up for good plays.
Sweltering Heat Transmission Field, Laval Cannoneer, Tender, and Laval Lady make the most noteworthy plays of all. Sweltering and Tender act as extra Foolish Burials for quick graveyard set ups, Lady clears out face-downs and sets up for Cannoneer who is used as Synchro Fodder with Laval Lady or Tender (both which can be banished thanks to Lady).
Both set ups are of moderate difficulty to establish and not that difficult to put up. What caught my attention was how both Deck Types have synchage with the Lightsworn Archtype. O_o both have OTKs with the archtype.
I have to say that I still prefer Laval200 as its easier to set up (IMO) is easier to pull off and most of the time the opponent won't get rid of a mass beater like Nova Dragon.
Lavals...are winning in my opinion.
Okay, I'm updating. Gishki vs. Lavals...so far, Gishkies prove to be flexible with quite a few other archtypes as well as stand out on their own, while Lavals seems to use Laval200 as their best deck.
