Search and synchro with Adamancipators while gaining the resources needed to Fossil Fusion, making liberal use of Time Stream if your opponent isn't running many monsters with levels.
Koa'ki Meiru monsters seem odd, but thanks to Adaman support and Doki Doki, they're incredibly easy to hit the field, with a simple maintenance cost for some decent negates, or simply level 4 targets for synchro summoning.
First deck list, so criticism welcome.
It's more for the casual level, despite the Adamancipator's appearance here, with a stronger focus on the Fossils.
