Stage 2 of the KaibaCorp Cup is coming this weekend. As such, this Tier List is intended to be moreso geared towards the Best-of-1 Ladder format.
Tier 1
TPC Comments
I expect Black Luster Soldier to get the most tops this upcoming KaibaCorp Cup, as this deck doesn't take too much time per game. Running Loading... will be good for stopping Loading... and other deck's combo starters.
We are in a KaibaCorp Cup meta where we generally expect hand traps (Loading... / Loading... ) to be included in decks. Black Luster Soldier is in an ideal position for this situation.
Black Luster Soldier looks to be the strongest deck this KaibaCorp Cup. It has the strongest engine and plenty of room for techs which can be changed at will during the KC Cup. With the potential to break most boards and play through backrow it's difficult to find something that can compete on the same level as it.

I believe Live☆Twin is just a solid deck. It has a 1-card combo into multiple disruptions, so I expect a ton of tops (as long as there aren't a ton of direct counters).
Live☆Twin is in a weird spot going into KaibaCorp Cup. On one hand, it’s super consistent and has the ability to easily draw into its ample tech cards. On the other hand, the sheer amount of decks in the meta could see Live☆Twins struggling to tech for everything. I think anyone hoping to succeed with this deck will need to have a keen eye on meta shifts and swap out their tech choices accordingly.
