Jet Synchron just got off the list, so I thought I look into Orcust again since they used to play Jet back in the day. And look at that it makes Orcust much more playable. What I want to show you is just the prototype since I don't know the correct ratios yet and I am also considering to go through other engines as well, just as dagda and souls.
The good thing right now is that halq is still legal, so we can use jet as a 1 card halq. But what do we do with halq? It's simple we get bombard and use it and halq to go into gala, then we can shuffle the Jet back and get an Orcust sp/tr. Now if we have an Orcust in hand we can extend further since we have bombard in gy. We also can play brave since we don't need our normal summon anymore, so say goodbye to bricky scrap golem combos.
Btw we can also use Small World, everything we need is a level 3 monster, then we use Terrortop as a bridge and get access to either Jet or Girsu aka the best cards in the deck.
I see alot of potential here and think that Orcust might be a rogue deck if not even a T2 deck. It just needs abit more testing.
