Yeah, I'm the dumb guy who tried to make Drytrons without Nova. There was no other way I could seem to build this deck without the use of Nekroz. The board it typically ends on is Unicorn and Ruler. I also tried to make the deck as budget-friendly as possible. So yeah as for things like Anima, you can just put a second Linkuriboh. And Nibiru can be replaced with a handtrap of your choice. Honestly, this is a more fun build that can be semi-competitive. If I had to make any recommendations, honestly just buy at least one Nova, cause it just makes the deck that much better, and also the reason I'm not playing terraforming.
The main combo is using Thuban and Aldhiban to special them and search for your Kaleidoscope and Ruler. Then you can search Unicorn off of many things, or add the Drytron ritual monster and ritual spell instead. Your board is going to try to look as good as suppressive as possible. You can use Asterism as another form of interruption, and that's mainly what Fafnir does other than searching the ritual spell.
As for side decking, You mainly want to replace the Fafnir for any handtrap or your choice. The other Drytron ritual monster can replace the other in case you are facing a backrow heavy deck. The Nekroz ritual monster replaces the Trish and the Mirror replaces Cycle based on preference. The other 6 slots can be used on whatever you want.
Please don't judge me for doing this, I tried really hard. Budget recommendations are appreciated, so yeah have fun with this deck.
