This is my perfected version of Paleozoic - with a dracotail package of 5 cards, the soldier dragon + laundry package as well as 2 sol now that he can't be sent to the GY by Sprind
I don't think there is anything here that could be cut unless you want to switch out Dogmatika Punishment for the third Canadia and another trap I'm running at 2 like IDP, or a third Time Tearing potentially. I wanted 3 Mirage, but really needed the 3rd Karma Cannon and wouldnt play Rollback or Trap Holic at less than 3, and Zeus is essential too so this is how I found it worked best. There are 2 draw traps in Balance of Judgment, which can be rotated out for Hope for Escape when going first to pair with Rollback.
Trap Holic + Mirage of Nightmare is just a game winning swing honestly, draw 4, pop Mirage with Trap Holic, chain a paleo etc
The side deck is just a guesstimate really, I like Dogmatika Punishment in main with Ulti Slayer in side with various targets - I did have Vallon here too but as I'm trying the Waking the dragons I thought that this could work well with the big towers guy. You can also use waking the dragon into Opabinia to turn on your in hand Paleos you draw off Mirage which is nice.
I've played paleo for a couple of years now and its always a fun deck. Just don't lose to time I guess. Dragon Gate helps with that to set up a big final OTK, and the Mosquito + Sol play can reverse OTK people in their battle phase if you save a paleo to summon in BP
The only other card I wanted to try was the new DOOD cont trap that mills 10, but it seems a bit win more here and hard to actually find from the deck
