Ancient Lord

The Ancient Lords are an high Level Effect Monster Archtype that rely on the Field Spell Card "The Ancient Paradise" and specific low power Normal Monsters. Their apearance are simulair to the Normal Monsters apearance that was used to Summon it, because it represends the ancestor of that monster (explaining the "Ancient" part of thier name). Their effect vary from Lockdown (Carcus Tartillu) to Protection (Tiror), Anti-Meta (Dungus Fii) and even Mill (Mantora Ente). But most of them have agressive Beatdown effects.

The Lords of Con
The Lords of Con are a subarchtype of the Ancient Lords and are summoned in a simulair fasion, however instead of using specific Normal Monsters and The Ancient Paradise, they use specific non-Effect Fusion Monsters and the Continuous Spell Card Ancient Citadel of Run Cot. These to are based on the ancestors of the tributed monster. As they are more difficuld to summon then the Ancient Lords, as they need Fusion Monsters, they have more powerfull effects and higher ATK/DEF. Mostly focusing on Burning and Swarming and summonable from the Extra Deck and also being treated as Ancient Lord monsters, they mostly serve as suplimental support.

Playing Style
The general strategy is getting The Ancient Paradise as soon as possibly out, then using its effect to tribute the specific Normal Monsters to get the Ancient Lords out as soon as possible then use thier effects to beat your opponent. So adding a lot of Field Spell searchers like Terraforming, Ancient Fairy Dragon, Demise of the Land and Envoy of The Ancient Paradise to play it as soon as possible. Then protecting it with cards like Field Barrier, Malific Stardust Dragon and Ancient Citadel of Run Cot, adding Ancient Citadel of Run Cot is also benifitial as you can then also add the Lords of Con. Normal Monster Support like Heart of the Underdog can also speed up the Summoning of the specific Normal Monsters. Stall cards might be a good choice aswell when you cannot Summon a Ancient Lord or Lord of Con directly.

Weaknesses
Thier dependance on the Field Spell Card The Ancient Paradise and low power Normal Monsters (or Fusion Monsters in the Lords of Con's case) is thier greatest weakness. If any of the requirements aren't on the field keeping the advantage is very hard. As all Ancient Lords need to be Special Summoned, cards that limit or stop that are also usefull when using against them.
