Notes & Combos
I played a similar list with 5 Mekk-Knights, submitted by the one and only Cydver, but I didn't like the Mekk-Knights too much, because I found myself having to set up columns too often, using my own spells/traps; there's just not enough benefit that way, since you can only plus if your opponent has enough cards in the column. Then, a user by the name of Valencia submitted a pure list with good 'ol little Formud Skipper. It was more along the lines of what I'm used to, and I just changed a few cards to my liking, namely Veiler instead of Ash, Mind Control instead of CBtG, and Change of Heart instead of Power and Crossout. Ningirsu for Unicorn is literally 4fun; it's worse in almost every way, but I love the World Chalice cards.
Parallel Exceed is amazing in this deck, allowing you to, dending on board state, go into an easy Dugares for doubling your Crusadia's current attack. Alternatively, if you're low on Crusadia names and the opponent's board is nearly wiped, Exceed is the only way to go into update jammer for the double Access Code attack, once you've popped their cards.
As a disclaimer, this deck obviously relies on clearing some of your opponent's board and OTK-ing. If you don't open a Kaiju or monster stealer, you're just not winning the game, barring the opponent playing with a bricked or semi-bricked board. Also, resolving Maxx "C" against Tearlaments or other summon-heavy decks makes OTK-ing a lot easier. On the other hand, as a blind-second deck, you don't give rat cheeks about Maxx "C", since you'll likely lose turn 3 regardless. Finally, Lightning Storm and Duster are super important, since this deck inherently struggles vs back-row decks.
Replays
Not sure if the replays I have saved are all that useful, tbh. You'll get the gist of the deck, though, I think, and I might add a couple more.
