When I first started playing Vanguard, I also started with the Star-Vader trial deck. I've made some changes to the deck, and it still needs a few changes still but, and I've got it to a point to where I'm happy with now.
My Star-Vader deck:
Grade 0:
Star-Vader, Dusk Tail Unicorn x1 (starting Vanguard)
Star-Vader, Stellar Garage x4 (heal trigger)
Star-Vader, Meteor Liger x4 (critical trigger)
Keyboard Star-Vader, Bismuth x4 (stand trigger)
Star-Vader, Nebula Captor x4 (draw trigger)
Grade 1:
Mana Shot Star-Vader, Neon x4
Prison Gate Star-Vader, Palladium x4
Homing Star-Vader, Fermium x4
Star-Vader, Aurora Eagle x2
Grade 2:
Strike Star-Vader, Krypton x3
Star-Vader, Pulsar Bear x3
Unrivaled Star-Vader, Radon x1
Star-Vader, Mobius Breath Dragon x1
Deep Shadow Star-Vader, Strontium x2
Singularity Sniper x2 (It's not a Star-Vader, but it will still be useful to you)
Grade 3:
Star-Vader, Francium x4
Star-Vader, Infinite Zero Dragon x1
Star-Vader, Nebula Lord Dragon x2
I want to put in a second Infinite Zero Dragon and Mobius Breath Dragon replacing (one) Francium and Radon, respectively. I also want to put in four Barrier Star-Vader, Promethiums in replace of both Aurora Eagles, one Neon, and one Fermium as well. And those are the changes I want to do for my deck from the cards that are out NOW! There's still several cards I want to put in my deck that haven't been released in America yet.
