The Triamid and Adamancipator half of this deck is nearly the same as this deck https://ygoprodeck.com/deck/triamid-321377 ; However we are not playing Doki-Doki or the Koa'ki engine.
This deck is more Triamid than Horus or Adamancipator. Only play this deck if you enjoy Triamid and would like to use them.
Rank 8's and Horus monsters, Level 5/7 and occasionally 8 Synchros alongside Triamid Field Spell loop to Triamid Sphinx
Use Ancient Fairy Dragon to give you access to Triamid Hunter through Triamid Cruiser. You can also access the Horus engine through Walls of the Imperial Tomb by destroying a Triamid field spell.
Garden Rose Flora has synergy with Triamid Field spells, triggering their effects when sent to the graveyard. This can search with Triamid Cruiser when you otherwise cannot get it into the graveyard. You can then go into a Level 7 Synchro with the Token summoned by Flora.
A nice interaction this deck has is summoning Black Rose Dragon while Dingirsu, the Orcust of the Evening Star is on your field. This provides a one-sided board wipe as Dingirsu detaches to protect your field. You can get to this from Garden Rose Flora as well as directly with Adamancipator Analyzer
Ideally, your Level 5 Synchro will be Naturia Beast, if you hard drew into your Field Spells and do not need to use Garden Rose Flora.
Triamid Pulse is an extremely valuable trap. Use it to destroy your opponents face-up cards, as well as special summon needed Adamancipator or Triamid monsters from the Graveyard.
Playing with this deck in Master Duel, working out changes. It certainly feels better to play than without the Horus cards. The deck can run into hand resource issues with the need to reduce hand size from Imsety, Glory of Horus, King's Sarcophagus, and Walls of the Imperial Tomb. There may be situations where you have to forego Triamid/Adamancipator plays to use the Horus cards and vice-versa.
