Soooooo about "Visas"....it can be pretty useful espacially if you open hands that would normaly be an absolute brick.
For example: If you open Visas + any Baby + Xeno Meteoros you can still go full combo. The Endboard is actually pretty massive and consists of the following cards: 1x Rank 6 + 1 Rank 4 + Chengying + Conductor + one random monster to pop for the effect of Conductor. (Keep in mind that this combo is very vulnerable to Nibiru because your first out against it would come up after the fith summon).
This is of course only how it could potentially turn out in theroy and recuires a test in practice first before I can blindly recommend the card.
The worst thing that can happen to you is that you end on only a "Baronne" which is still better than ending on nothing at all.
The Megatins made this card really cheap now, which is one more thing to consider.
The Bystials are great for enabling more rank six plays. Drillignathus is a generic rank 6 which I overlooked first. So technically you could extend your plays with two bystials and special summon a banished dinosaur monster!
I cut the scrapengine because most hands turned out to be too bricky.
Endboards:
Most endboards will result in 1x Lars, 1x Dolka or Laggia, 1xTyranno and Secure Gardna. So five interruptions in total.
Another possible endboard would be 1x Baronne, 1x Dokla or Laggia, 1x Tyranno and Secure Gardna.
Even suboptimal hands can result in either one Lars, Laggia, Doklka or Baronne +1x Tyranno and Secure Gardna.
Conclusion
I absolutely love this build and I think oftentimes people unterestimate Dinos because it is not a "Metadeck".
"Chengying" is a absolute powerhouse for ending games especially in combination with "Ultimate Conductor".
I am debating on cutting the Gigantozauler and Crossheep since they only came up once and it didn`t really made a difference on the endboards.
"Triple Tactics Thrust" can improve this build even further as it can almost search every spellcard in this deck.
