Always go 2nd.
Adamancipator for special summoning engine and Link Summoning material.
Be ready to summon Verte Anaconda to summon Dragoon after Fossil Fusioning, and it's equal to filling your grave with Rocks.
You have basically 4 Foolish Burial (-----3 Miracle Rupture-----).
You have basically 4 Special Summoning from grave (Monster Reborn + 3 Adamancipator Signs).
Fill your grave with Rocks. Discard Weathering Soldier to add Fossil Fusion.
Don't worry with Ash Blossom, etc. It's like your Fossil Fusion material.
Nibiru is Rock-Type.
For Synchro Monster, I still don't know what to play.
The Fusion Monster is badass and beating down opponent.
Semi-burning tho lol.
