This list attempts to use Kaiju's removal with Krawler's control to play a very defensive going-second build. We want to slow down the game to a pace we can control and use our board-breakers and stun tools to keep the opponent from being able to meaningfully interract with our board. This is a part of a series I'm working on where I try to build as many variants of Krawler as I can. I'm doing so to stretch myself creatively, and to get to know the archetype better. I'll be going over what Krawlers do well/poorly, what the blending of these archetypes brings to the deck, as well as a card-by-card of the most notable additions to this list. This list was made possible by contributions from the Krawler discord, and user Marowak2000 in particular, so many thank!
Alright, Krawlers: what do they do well, what do they struggle with, and what does their partner in this build (Kaiju) bring to the table? Krawlers have a very strong grind game. Each Krawler you get to stick on field is a renewable effect to either pop a card, summon a Krawler from GY or hand, or to return 2 cards from GY to hand (just the Krawlers in this list). They can flood the board, thanks to Soma, and have a strong Skill Drain monster in Deus X-Krawler, not to mention all of the Krawlers (except Soma) float into more Krawlers! The downside is that these are still flip-monsters, and as such they needs lots of support to get the best out of them. A going-first build has to contend with the opponent's hand traps and interruption as well as board clears like Lightning Storm, Raigeki, and Harpie's Feather Duster. Kaijus help the Krawlers generally slow, setup-oriented gameplan by allowing us to go second. We let the opponent make their best board, and then we Dark Ruler, Interrupted Kaiju Slumber, and just plain old Kaiju the opponent's best sources of interruption before making our board. By going second, we avoid the most damaging removal for Krawlers (when they're face-down and can't float), and get many of the opponent's most powerful mosnters out of the way. One of the main risks of this approach is if the opponent is playing a Trap/Quickplay deck like Labrynth or Runic, in which case we will need to side into other board-breaking options.
Our Kaiju package is 2 Gadarla, 2 Gameciel, 3 Interrupted Kaiju Slumber, 1 Kyoutou Waterfront (for the grind game), and 1 Thunder King (searchable off of Deus X-Krawler's floating effect).We're on Beetrooper Scale Bomber and Magical Hound as our Small World bridges, but they both do work for the deck; Scale Bomber is an extender and Magical Hound can bounce a floodgate. We are on 1 World Armor for a Girsu line ending on Equimax, using our 1 World Legacy Succession. We are on 1 Knightmare Corruptor Iblee to further control our opponent's board, but she may not be necessary. We are on 2 World Legacy Mind Meld, usually to send off of Girsu to guarantee Deus X-Krawler, and we play 2 copies to lower the chance of drawing both. The three flip Spell/Traps in this list are played at 2 each: Sol and Luna(EDIT: now at 3), Junk Sleep, and World Legacy Pawns. I'm considering lpaying Sol and Luna at 3; it is a hard once-per-turn, but it is invaluable in breaking boards and activating Krawler flip-effects (I've since updated the list with Sol and Luna at 3). Junk Sleep has niche uses when we want to activate more than one Krawler at once, and it flips all of our monsters face-down at the end of each turn, which is a great way to re-use Soma's effect. World Legacy Pawns only targets one monster, but it is searchable off of Lib and Survivor, and it can be activated more freely than Junk Sleep's reactive activation. In the extra deck we have the usual suspects like I:P Masquerena, Avramax and the Knightmares. Since we are going second, Dharc can often steal a card out of the opponent's GY. We can make Wina off of two flip-monsters and Girsu, using Shaddoll Construct to perform the fusion. Gigantic Spright lets us set up the Iblee line and link off into Dharc, I:P Masquerena, or another Link 2.
Our main line of play is, as said above, going second. If we open Dark Ruler, IKS, or Kaiju(s) we can pressure the opponent's field and remove their most critical monsters. Once we have done so, we need to mop up the rest of their board. We have a few options for this, most of which start with Girsu. Normal Girsu, pitch Mind Meld, make the Girsu token, use Soma to flip Girsu face-down and summon Soma. Activate Soma to summon 2 more face-up Krawlers from deck, link Soma and the token for Lib, activate Lib to set Pawns, link the small Krawlers for Shaddoll Construct and make Winda with the Construct and the face-down Girsu. This line is only beneficial if you cleared most of the opponent's board before going for it. If the opponent still has a lot of threats still in play, start instead by normal summoning Girsu and sending World Armor to the GY. Make Lib (Soma/Girsu token) and search Succession. Activate Succession summoning back World Armor, and searching Survivor/Pawns/Mind Meld (depending on what you need). Link off for either Avramax or Equimax and attack the rest of the opponent's board. If we start with Soma and another normal-summonable monster instead, we summon the monster, activate and summon Soma, and use Soma to summon 2 more Krawlers from deck. Link off for I:P Masquerena, then Equimax, attacking into the Kaiju you positioned so that Equimax would be pointing to it. Other plays we can make to clear boards include setting Spine and using Sol and Luna to flip Spine up and an opponent's monster face-down, then using Spine to pop an opponent's monster. To use Iblee, we need Soma and any normal-summonable monster in hand. Normal summon, then special Soma by flipping that monster face-down, use Soma to summon 2 Krawlers, either 1 face-up or both face-up. Overlay for Gigantic, use Gigantic to summon Iblee, then link Iblee and another monster off for any Link 2 monster, summoning Iblee to the opponent's field.
