Another special 60-card set has made its way to the Yu-Gi-Oh! TCG, introducing brand new themes to the game. Ancient Guardians introduces a graveyard-based Reptile deck that can make the most use out of the classic Snake Rain. This as well as a Synchro deck that subtracts levels to summon their Synchros and a Pendulum deck that uses their Pendulum Scales in a totally new way.
The set contains 10 Ultra Rares, 15 Super Rares, and 35 Rares. Additionally, Collector's Rare will make an appearance in this set with 15 cards available in this rarity.
With the existence of a card like Snake Rain, duelists have been looking for a deck that can utilize that card to its full potential. Finally, after many years, a deck like that makes its way into the game. Ogdoadic consists of both LIGHT and DARK reptile-type monsters that focus on manipulating your graveyard. One of their starter cards is Nunu, the Ogdoadic Remnant: a level 4 LIGHT Reptile that can send itself from your hand to the graveyard to send another Reptile from your deck to grave. Graveyard set-ups in a graveyard-based deck are always great, but Nunu's second effect lets it Special Summon itself from the grave if you control no monsters or only Ogdoadic monsters.
Nunu's counterpart, Nauya, the Ogdoadic Remnant, is a DARK Reptile on the other hand that can send itself to the grave from your hand to send a LIGHT Reptile from your deck to the graveyard. Additionally, when Nauya is summoned, it sends an Ogdoadic Spell or Trap from your deck to the graveyard.
The most powerful spell is most likely Ogdoadic Water Lily, a Foolish Burial for any of your Reptile monsters with an added effect of Special Summoning any of your Reptiles from the graveyard if it contains five or more Reptile-types. In other words, an ideal follow-up after playing Snake Rain. The bigger Ogdoadic monsters like Aron, the Ogdoadic King and of course the cover card, Ogdoabyss, the Ogdoadic Overlord, can also Special Summon themselves from your graveyard like Nunu and Nauya, but require tributes to do so. In return, however, they grant you powerful effects like sending a card from your opponent's hand to the graveyard when they add a card from the deck. Or, in Ogdoabyss' case, destroying all monsters on the field except the ones that were Special Summoned from the graveyard!
Ursarctic is a new Beast- and Beast-Warrior type Synchro theme heavily inspired by the Big Dipper constellation. All of their main deck monsters are level seven or higher, but during the main phase, can be Special Summoned from the hand (as a quick-effect) by tributing another level 7 monster in your hand, enabling you to swarm your field during your opponent's first turn. The most interesting part of this new archetype is that it subtracts levels, instead of adding them up to Special Summon their Synchro monsters.
The best example of this is the level 1 Synchro monster, Ursarctic Polari - the first one of its kind. This little mecha bear is Special Summoned by sending one tuner and one non-tuner you control to the graveyard, whose difference in levels equals one. Upon being summoned, Polari activates the theme's Field Spell, Ursarctic Big Dipper, straight from your deck. This Field Spell allows you to banish monsters from the graveyard instead of tributing from your hand to activate the effects of your Ursarctic monster, allowing you to continue Special Summoning Arsarctic monsters after you went through the cards in your hand.
Ursarctic Septentrion is their boss monster, and just like Ursarctic Polari, it is Special Summoned by substracting the levels of its materials. One way to summon it like this is by using Polari (level 1) with the tuner Ursarctic Megapola (level 8). Serpentrion negates the effects of all monsters Special Summoned from the extra deck that do not have a level and lets you search your deck for any Ursarctic card when your opponent Special Summons a monster.
