Notes & Combos
Make no mistake, this deck has gotten a LOT harder to play with the introduction of adventure stuff, more experimentation on board breakers will be needed, especially since golem and sphere mode can't really be used due to reliance on normal summon. I do not recommend solely climbing with this, instead I recommend having another, more powerful deck to fall back on to prevent deranks or just to let loose some steam. You can definitely contest meta decks with a good enough hand tho, or just having the right interruption at the right moment.
Small World vs Pot of Desires is down to preference mostly. If you choose to run small world, ogre and nib are mandatory, as they both make bridges for other cards, you can check the Railway channel pins for common small world lines. You can run Ghost Belle and Exodius for alternate bridges, just keep in mind space is a bit tight for more hand traps.
3x Gadarla 2x Jizu instead of other way around to maximize chances of drawing gadarla against flunder, but you can also hard deny them by running droll, once again keep in mind the space for cards in this deck is kinda tight, already super close to cutting in on engine pieces as is.
The extra deck is pretty flexible, only required ED monsters is the ironwolf, gustav, ganga, liebe, zeus, underclock, and pentestag, leaving you with a good 5 slots to find tech choices, stuff like knightmares are definitely not out of the question.
