Notes & Combos
The extra deck is just filler, you ideal would want another copy of Justify. I just added generics that were avaliable for the event. You do not go into the extra deck often so in place of all these fusions, if there are any other generic extra deck monsters you can play them.
Generally you want to go into Edea from both ROTA or Reinforce Truth that gets you into Rappa Chiyo. From there I like to banish Gravitino so you can get her back with Pla-Tina. Since you don't always have the Gravitino to banish you can use any S-Force including the recent Retroactive if it's in your grave (also works with Chase in GY). Off Gravitino search I like to grab Bridgehead if I need another monster or Chase for the disruption. Make sure Gravitino/S-Force monsters are in the same zone as your opponent's so they get banished on return.
Dog-Tag I think is just not neccesary. 1 copy of Showdown because you can add back Lapce, but honestly just summoning him back gets you stuff from grave anyway. If you have the Edge Razor you can get into anything in hand.

A handful of games, nothing that really stands out: https://youtu.be/vC3txpcrTHk
