Got 3rd at the 3rd mst.tv open series tournament which was pretty sweet. It's an unofficial tournament for our area/province as there hasn't been a regional in 4 or 5 years and these unoffical tournaments have basically replaced them, they kick ass in prize support too, get a play mat for top 8 and store credit. The tournament was about 70 people so not too massive, I played against tons of meta though. Played 4 mirror matches (won them all), 2 monarchs (one extra deck one normal), psy-frames (lost in top 4 to this, my friend/testing partner who I went with piloting them and they are not an easy match-up), mermail (my loss in swiss, every game ended turn 2), and burning abyss. They do feature matches on their channel and they had me in one of them and a deck profile so those will probably be up there at some point: https://www.youtube.com/user/MSTTV604/videos
This is my half report-half deck list.
3 Kozmo Dark Destroyer
2 Kozmo Forerunner
2 Kozmo Landwalker
2 Kozmo Sliprider
1 Kozmo Delta Shuttle
2 Kozmoll Darklady
1 Kozmoll Wickedwitch
2 Kozmo Soartroopers
3 Kozmo Tincan
1 Kozmo Farmgirl
2 Kozmo Strawman
2 Maxx " C"
1 Fire King Avatar Garunix
2 Radian, The Multidimensional Kaiju
2 Emergency Teleport
2 Allure of Darkness
1 Fire King Island
3 Call of the Haunted
1 Vanity's Emptiness
Total = 45
To explain some choices, the reason I play 45 cards for one is that I found in the fire king island build it is really hard to find room for defensive cards and tech choices such as maxx "c" and the kaiju. I just decided to say screw it and go over 40. In theory this means I should draw into my garunix less as well. I only opted to play 1 fire king island as I only ever wanted to use it just once in a duel, and additional copies would make me feel like I would have to add in more fire king monsters which I really did not want to do as I tried that at first and it led to really bad hands. I basically have 4 copies of island due to terraforming compared to 6 if I add additional fire king monster bricks, I don't think the payoff of 2 extra copies is worth the potential brick hands. Drawing multiple island together can be kind of mediocre too.
For dark lady, yes you need 2. At first I thought I just needed one but after testing I feel at least 2 are needed. Being able to dump one with tincan so you can soartrooper it back later is good while also being able to summon one off of a level 6 or higher spaceship. Also a random note is in the mirror match I would let my opponent get whatever to their hand with tincan and just wait until they try to summon a spaceship and just OTK them before they could play whatever they got to hand.
The best combos with fire king island are with level 6 or higher spaceships, so I use more copies of forerunner and 2 copies of landwalker over the 3rd sliprider and other potential spaceships that could be run. More than 1 delta shuttle isn't really needed, and any combo that would involve 2 of that thing is probably unnecessary in my opinion. Also landwalker is a dark so it can be used for allure of darkness and can protect things like strawman, soartroopers, tincan, or dark lady which can be a nuisance for the opponent. More than 2 soartroopers is also unnecessary, you can still do crazy double leviair shenanigans with just 2.
The traps are another reason I went over 40. To be able to fit in cards like kozmojo which are amazing in the mirror match still is great. Seriously, do not run less than 2 kozmojo under any circumstances, and I did not care if I had to go over 40 to do so. The card is way too good to not play. A lot of the time going first with a level 6 or higher spaceship and a kozmojo was a win in the mirror match. Just mojo their first attempt to summon something then bring out dark lady to negate a potential second attempt. Vanity's emptiness is also a free win in the mirror match a lot of the time now as it is difficult to find space for spell and trap removal in the island builds.
The main deck kaiju monsters were amazing and bad sometimes. It was good as one monarch player dropped majesty's fiend and march of the monarchs turn 1 so dark hole or raigeki wouldn't have been good enough. In the rogue match-ups it wasn't very useful at all though, it is solid vs burning abyss, monarchs, and the mirror match though which were the 3 match-ups I mainly cared about. I also hit a couple dark ladys as well. They might come out or move to the side deck, I am not completely sure yet. Also the reason for playing radian over other kaiju is forerunner can crash with him and you can use it for allure of darkness.
For overall changes I am not really sure, but I do want to get it closer to 40 if I can. I think 3 tincan is still solid as if you don't open fire king island it is the next best thing. The deck is definitely not perfect and could use work, but I don't think we want to opt out of including cards such as maxx "C", kozmojo, or vanity's emptiness in order to get down to 40. There are definitely some cards that could be trimmed such as the 3rd kozmotown possible, I found myself siding that out to make space a lot.
Also the side and extra deck weren't too interesting, other than the 3rd sliprider, maxx "C", and 2 ghost reaper and winter cherries, mask of restricts, it was pretty standard. Might swap the 2 magic deflector for solemn strike for the mirror match when going first. Extra deck noteworthy thing is double leviair which I went into against burning abyss as I brought out utopic 0 and cyber dragon infinity with soartrooper shenanigans to steal 2 of beatrice for game. Other thing is the rank 3 super-quantal for popping your own kozmo town which can search kozmojo, or potentially extend your combos. Also dante because of cherries.
