Hydralander Flip Control

Flip Control is a grindy toolbox deck that uses floodgates to slow games down enough that cards like Subterror Succession and the Shaddoll engine can gain an overwhelming amount of advantage.

The fiend engine adds Tindangle Jherlth, which can discard another card and send a Tindangle, which will be Tindangle Intruder, from your deck to special summon itself, then if Intruder was sent to the graveyard it will summon itself. On flip Jhrelth can add or send any flip monster and Intruder can search Tindangle Angel.

The Subterror engine can get to Subterror Guru which can add Subterror Fiendess for a negate, Subterror Volteluric can allow you to make Thunder Dragon Colossus, or Subterror Succession which gives us access to our other engines.

The Shaddoll engine gives us access to the powerful Fusion monsters but the main deck Shaddoll monsters are especially powerful in this deck as disruption and incredibly sticky monsters. The Dogmatika package allows us to access the Shaddoll engine through El Shaddoll Apkallone's graveyard effect.

Floodgates like Summon Limit and There Can Only Be One and board breakers like Needle Ceiling and Nibiru, the Primal Being are especially good in this deck because it uses a lot of set monsters which are unaffected by these floodgates, and these floodgates also slow the game enough that one or two disruptive flip effects a turn cycle can turn the game in your favour.
