"true Call of the Atlanteans" Deck 2013

Playing

This is the [Atlantean] Deck with "Legendary Atlantean Tridon" and "Waterfall Dragon Ruler - Tidal" that appeared in "LORD OF THE TACHYON GALAXY". His low-level Atlantean monster, which appeared in the same structure deck, synergizes tremendously with his Mermail and Genex Undine, making it one of the top decks in the format. However, "Poseidra, the Atlantean Dragon", which is the signature monster of the Structure Deck, was not put into the Deck much because it was an accident factor and an effect that was difficult to use.
However, with the arrival of Poseidra's infant Tridon, Poseidra can now be used as the ace of her Deck. In addition, by including "Water Dragon Ruler - Stream" that can search for Tidals and Tidals of Level 7 WATER, which is the same as Poseidra, you can aim for a Rank 7 Xyz Summon while activating Atlantean's effect.

Strength

Tridon's effect is to release itself and Sea Serpent monsters on your field, allowing Poseidra to become her Special Summon from the Deck. Then, after using this effect to Special Summon Poseidra to her, her ATK of monsters on the opponent's field is lowered by 300 points.
At first glance, it seems difficult to line up Tridon and a Sea Serpent monster as they are, but Tridon is her level 3 Sea Serpent monster, so you can recruit it with the effect of "Deep Sea Diva". Normally, it would lead to a Level 5 Synchro Summon, but here, with the effect of Daeva and Daeva, he releases Special Summoned Tridon, allowing him to Special Summon Poseidra from the Deck. Due to Poseidra's own effect, if he wanted to Special Summon, he would have had to release 3 of her Sea Serpent monsters of level 3 or lower, and had to use support cards such as "Call of the Atlanteans", which made summoning very easy. can be said to have become By the way, if there are monsters on the opponent's field after summoning Poseidra, Tridon's effect will reduce her ATK, so you will miss the activation timing of "Bottomless Trap Hole". As a result, Poseidra that was Special Summoned by Tridon's effect can be Special Summoned without affecting 《Bottomless Trap Hole》.
However, even though it won't be removed by Bottomless Trap Hole, the summoned Poseidra will become vanilla with 2800 RBI, so instead of leaving it standing as it is, Special Summon the same level 7 Tidal and connect it to a rank 7 Xyz. let's
The rank 7 used in this Deck is water bound, but has a strong suppression power "Mermail - Gaio Abyss", removal effect + gain resistance under certain conditions "Mecha Phantom Beast Dracossack", permanent control seizure effect "No 11 Big Eye” and powerful monsters, so let’s aim for a beatdown by adding these monsters as well.

Weakness

Tridon can Special Summon with Diva's effect, and Poseidra can Special Summon with Tridon's effect, so if Tridon and Poseidra come to your hand, it will be difficult to summon as soon as possible (Poseidra can be used at the cost of "Sacred Sword of Seven Stars". but...). Send "Atlantean Dragoons" to his GY with the effect of Tidal or Stream, and search for cards such as Diva that can Special Summon Tridon.

Customize

This time, he focused on Atlantean, but if you combine it with Mermail, it will generate even greater synergy.
He can send Poseidra and Tridon from his hand to GY with the effect of "Mermail-Megalo Abyss", so I think it will reduce the accident rate a little.
