Your turn 1 endboard should look like: Rusty Bardiche, Arsenal Falcon and Masquerena. Optionally, Full Armour Master, Borreload Dragon, or any other fodder Synchro.
Masquerena into Unicorn (or Avramax, if preferred and have an extra synchro on field) using Arsenal falcon, activate Arsenal and bring Ultimate falcon out, use Unicorn effect and Bardiche effect on their turn.
