Now that Generaiders are consistent AND good (and more importantly, have a sexy dommy waifu boss), and it's Spooktober, I finally decided to get around to posting this deck, one I actually have all the cards for. Before Vala, the gameplan was to get Boss Stage on the field afap, so you wanted the deck no bigger than the minimum, but with Vala that becomes the alternative. Now you can play proactively as well as reactively. After all, you can't Xyz Laevatein on your opponent's turn. I needed more level 9s to not brick on Vala, but the rest of the deck was too crucial to give up, so I slapped in two more. The deck doesn't technically need 3 Mardels, but I'm not putting in another Utgarda or a third of any other. And this way, you can combo off faster. Previously, I also ran 2 Hela, but she only pluses when you have tokens on the field. She is just here as another target. Same with Dovelgus, though he's already helped me out a lot.
With Boss Quest, you might be tempted to grab Stage and Room, but if you know your opponent is running a lot of removal, better grab that Fight instead for a backup Stage. You only really want to use Room's effect on a turn you Droll & Lock. Mardark is a level 9 that Theurlogical Demiurgy can summon. It debuffs enemy monsters, and recycles a Generaider for you to recycle Vala. It's also a wind monster for Link God Dragon. Condemned Witch nets you a Forbidden spell and summons Loptr on opponent's turn (this is not a combo I discovered). I pulled 1 Droplet from my Rise of the Duelist box and got the Chalice in a structure deck, and I am not about to buy more. 1 searchable copy of each fills this deck's needs anyway. Trias Hierarchia is a quick effect you want to use the tokens for. Kuji-Kiri Curse lets you use any level 9 from your hand or field, which can free up space to proc Vala for a new turn.
Now, I know I've said before that I don't like running handtraps in a deck if I can fill that space with engines instead, so some of you might be thinking, "Hey Flooffy, why do you have Droll & Lock Bird here?" I'm gonna tell you a story. Back when I thought I would keep going to tournaments (before I realized how massively my last opponent cheated at my last one), I started buying up playsets of every handtrap reprint I could get, because they were reprinting like flies that year. Droll was only $2 each at the time. It sat in my tin, useless to most of my decks, until I noticed how applicable it is in Generaiders. Unlike almost any other deck, they can choose when the Droll & Lock activates. Instead of letting your opponent plus from all those draw 1 Generaider effects (something you only want them to do if you are playing a draw burn deck, like the casual Trickstar Generaider deck I concocted, which makes Frodi usable and I will post if anyone shows interest), they get stopped at +1 and won't get to search anything either. It also essentially turns Boss Room's effect into "negate that effect". Just remember you can't proc Jormungandr or Mardel after you do that.
Trickstars Foxglove Witch and Divaridis are remnants from that Trickstar Generaider deck because Foxglove is the only one that can be linked using generic Fairies (Loptr, Condemned Witch, Vala), and she summons Divaridis on death. I would save this for when you can end your opponent with the burn damage and their board is too pesky to attack or play through otherwise. The rest of the extra deck is filled with Xyz and link monsters you can summon, with plenty of big beatsticks for those obnoxious monsters unaffected by effects.
The side deck is full of alternative cards I mostly don't have, which all revolve around Mereologic Aggregator. He's a rank 9 that sends an extra deck monster to the gy on summon. The other cards in there do something if sent to the gy. N'tss: Target & destroy 1 card; Malong: Target & return 1 opponent's face-up card to the hand; Garura: Draw 1; Camellia (not yet released): Target 1 opponent's monster, ss her to their field, send targeted monster to gy, get control of her in end phase (says "must first be link summoned", don't know if that applies to summoning on your opponent's field, and switching control is not summoning); Kaleido-Heart: Ss her, then target and shuffle 1 opponent's card (I actually pulled one from a blister at Walmart, so I'm really excited to use her). You could just play it safe and only run monsters you can summon naturally by bumping up Aggregator to 2, using him to proc his own gy effect faster.
If there's one card you can cut from this deck, it's Boss Room. I just like the interaction with Droll & Lock.
