Constellars.... Pretty much same as Evilswarms , only difference is their attribute is light. Pollux is same like Castor , sombres is same like cercyon.
They focus on modulating levels to get out rank5 xyz's ( Pleiades / Tiras / Adreus / Zenmaioh ).Also , they can easily get out rank4 xyz's (Omega / Photon Paradios).


Main Cards

Constellar Pollux (Lvl4 , Warrior , Light)
During the turn this card was Normal Summoned, you can Normal Summon 1 "Constellar" monster in addition to your Normal Summon/Set. (You can only gain this effect once per turn.)

It works like Evilswarm Castor. Most of the time its effect is used with Kaust ( Summon Pollux , coz of its effect you summon kaust from your hand , then modulate levels and get out pleidaes or just go with omega)It's searchable with Reinforcments of the Army.Also , if you have Pollux , Gredi , Sombres in your hand and your opponent has face-up monster. You can summon Pollux , then again normal summon Gredi , then Special summon sombres from your hand , xyz to photon Paradios with gredi and pollux , use its effect. Then activate sombres effect and just re-summon kaust/gredi (depends which one you put in your hand from your graveyard.)


Constellar Kaust (Lvl4 , Beast-Warrior , Light)
Cannot be used as a Synchro Material Monster. Up to twice per turn: You can target 1 "Constellar" monster on the field to activate 1 of these effects;
● Increase its Level by 1.
● Reduce its Level by 1.

Only way for you to get out rank5 xyz's is with this card's effect.Basic combo is Pollux and Kaust to get out Plaedies/Tiras/Adreus/Zenmaioh.


Constellar Gredi (lvl4 Spellcaster Light)
When this card is Normal Summoned: You can Special Summon 1 Level 4 "Constellar" monster from your hand.

Basically the same as Pollux.


Constellar Sombres (lvl4 Fairy Light)
You can banish 1 "Constellar" monster from your Graveyard to target 1 "Constellar" monster in your Graveyard; add that target to your hand. You can only use this effect of "Constellar Sombres" once per turn. Once per turn, if that effect was activated this turn: You can Normal Summon 1 "Constellar" monster, as an additional Normal Summon. If this card is in your Graveyard because it was sent there this turn, you can Normal Summon 1 "Constellar" monster with 1 less Tribute than required. (You can only gain this effect once per turn.)

Same effect like Evilswarm Cercyon. You need 2 constellar's in graveyard to use its effect ( remove from play one , and add an constellar from graveyard to your hand and then you can normal summon +1 constellar from your hand). Usually used to get Kaust and going into rank5 xyz , also can work with rank4 xyz ( omega and others )


Constellar Sheratan ( lvl3 , beast , light )
When this card is normal summoned : You can add 1 "Constellar" monster from your deck to your hand.

This card is the only lvl3 in this deck , it's a searcher for Constellar monsters. It's used to get Sombres/Pollux/Kaust to your hand, but it depends on the situation you're in.


Constellar Ptolemy Messier 7 ( Rank6 , Machine , Light )
2 Level 6 monsters
You can also Xyz Summon this card by using a "Constellar" Xyz Monster you control as the Xyz Material, other than "Constellar Ptolemy M7". (Xyz Materials attached to that monster also become Xyz Materials on this card.) If you do, its effect cannot be activated this turn. Once per turn: You can detach 1 Xyz Material from this card to target 1 monster on the field or in either player's Graveyard; return that target to the hand.

Basically , when you run out of xyz materials on your "Constellar xyz's" , you just Xyz Summon this card by using a "Constellar" Xyz Monster you control as the Xyz Material. Examples : Omega / Pleiades.


Constellar Pleiades ( Rank5 , Warrior , Light )
2 Level 5 LIGHT monsters
Once per turn, during either player's turn: You can detach 1 Xyz Material from this card to target 1 card on the field; return that target to the hand.

This card can only be summoned with having Kaust + other constellar on field. You use kaust'es effect and make 2 of your constellars lvl5 , then xyz this card. This card is good because with it you can recycle your fiendish chains / tenki's and also slow down your opponent because you can use it's effect during your opponents turn aswell. (You can keep messing up your opponent's plays.)


Constellar Omega ( rank4 , Beast-Warrior , Light )
2 Level 4 LIGHT monsters
Once per turn, during either player's turn: You can detach 1 Xyz Material from this card; this turn, face-up "Constellar" monsters you control are unaffected by the effects of Spell/Trap Cards.

You can get him out easily on the field. You can use he's effect during eithers player turn which makes him un-effected by effects of spell/and traps , after you run out of xyz materials on him you just xyz summon messier using omega as xyz material.

Fiendish Chain


Deck Skeleton

3x Constellar Pollux

Weakness

Rivalry of Warlords
This card can kill Constellars on its own because all of them have different type (Beast / Warrior / Beast-Warrior / Fairy / Spellcaster)

Light-Imprisioning Mirror
Stops them all from using effects, also not allowing Kaust / Gradi / Sheratan / Sombres / Pleiades / Omega to use their effect's.

Thunder King Rai-Oh
Stops them from searching with Tenki / Rota / Sheratan. It also doesn't let them xyz because you can negate.

Skill Drain
Same as Light-Imprisioning Mirror - Stops them from using effects and eventually kills them.

Effect Veiler
This card is good against pretty mutch every deck. It slows constellar's down (Sheratan / xyz's / Kaust / Sombres)

nice guide

Awesome I was always a Fan of Constellars

This guide will Help meh Improve it a bit xD

well done Patrol xD

interesting

It's a bit short . Also what I don't like is when you start explaining an effect monster from the type , you mention all the options you can summon with it , which is a bit unnecesary .
You can also try to fit a joke here and there  

Great Guide , Almir
