Fellow Kagero player here, much respect to your full LR Perdition deck. Perdition isn't really competitive now, but that sure is terribly difficult to build. Kudos :)
Im happy to see im not the only person who makes all types of deck my friends and bro tell me you should always focus one haha but hey man i have 23 my self missing a few clans but you have a great collection man really
you should have some dimension creepers in you Dark Irregulars deck, when attacking with gilles, put all (preferably 4) creepers, to the drop zone, that way, you can soul charge 8, and doreen the thruster gets +24000 right of the bat, and the final attack power will be 50k, 2 crits, and no nulls for the opponent
buy 2 trial decks. most people like to start off that way and now it's easier than ever. all the vanguard g trial decks come with 2 boss grade 3, 2 staple grade 2 and 2 perfect guards. buy 2 and get some good commons and rares and you're good. most people i've met in the vanguard community are pretty nice. they'll help you build a more competitive deck once you get more into the game.
