Still not overly sure if i'm happy with the build, but I think i'm taking it in the right direction.
Uria/Armityle/Dimension Fusion are really just there for personal flavour and the deck would probably be a lot better if they were cut. The Scorpio/Cobra package does make Army more consistent because the fusion spell is then more searchable without sacrificing looking for your more important cards and then they can be used to summon Verte - Dragun. BUT i'm not overly sure I like them in (Scorpio/Cobra not Verte/Dragun) so they can probably be cut in favour of cards that actually do something.
Triples of Beckoning, Chaos Summoning and Spirit Gates because the search is just brilliant. I like 2 Sky Fires and Awakenings just so there's more chance of you getting them and not losing them to Desires, also nice to have extras incase they get destroyed.
2 Fallen Paradise, super easy to search it out and it provides brilliant prot/draw power. Could probably take it to 3 if you want but I think 2 is plenty. 2 Summoning beast, it's the weaker of the summoning cards but by no means useless.
Upstart, double Allure and double Desires because you love drawing cards in this deck, gotta get a hold of those summoners as quick as you can. Double Ash and Crackdown just because. I think the deck is fine going over 40 cards because there's so much draw, and almost all the cards are searchers so having that bit of extra protection cards in the mix I feel helps out without diluting the deck.
