Cloudian " Cloudian " ( " Kuraudian " ) is an archetype of monsters used by Adrian Gecko in the " Yu - Gi - Oh ! GX " anime . All members of this archetype are WATER Fairy monsters , except for the following : They were introduced in " Gladiator ' s Assault " , with further support in " Light of Destruction " . Most of these monsters cannot be destroyed by battle while in Attack Position , but if in Defense Position they are destroyed via their own effects . Most " Cloudians " have their effects activate d or become active while they have Fog Counter s . Playing style . " Cloudians " require an advanced degree of skill to use properly , because their usefulness depends on how many Fog Counter s there are on the field . Most " Cloudians " cannot be destroyed by battle , but their low ATK leaves their controller open to taking damage unless " Spirit Barrier " or " The Sanctuary in the Sky " are used . Once your support cards are in play , the opponent will find it frustratingly difficult to get past a " Cloudian " Deck ' s defenses . While the opponent is being stalled , the " Cloudian " user can then generate enough Fog Counters to whittle down the opponent ' s defenses , eventually leaving them with nothing to protect themselves from the otherwise " weak " monsters . A " Cloudian " Deck can focus on swarm ing the field , on destroy ing the opponent ' s cards , on inflicting effect damage with " Natural Disaster " , on a Stall Victory , on raw Beatdown power with " Cloudian - Nimbusman " , or any combination of the above . " Cloudian - Eye of the Typhoon " can also provide some field control by messing with the battle position s of opposing monsters . The seemingly weak monsters in the Deck such as " Cloudian - Altus " , " Cloudian - Cirrostratus " and " Cloudian - Acid Cloud " become surprisingly useful with enough Fog Counters on the field . Through cards like " Cloudian Squall " and " Fog Control " , anyone facing these three puff - balls will quickly find themselves with no monsters , no back row , no hand and no options . Hence the name : " Cloud Control " . A killer combo can be made by using " Cloudian Squall " to put a Fog Counter on " Cloudian Turbulence " every turn . Then you can play a " Cloudian Smoke Ball " and tribute it to play " Mecha Sea Dragon Plesion " , and every turn tribute the " Smoke Ball " that you can play each turn to devastate your opponent ' s field . Also , since most " Cloudians " are Fairy , a good card to add is " Athena " , who can use her effect to Special Summon powerful " Cloudians " from the Graveyard by sacrificing smaller " Cloudians " like " Cloudian - Smoke Ball " . While the Special Summoning is generally a good idea , bear in mind that most " Cloudians " gain their Fog Counters when they are Normal Summoned . The effects of the " Cloudians " work when they have enough Fog Counters to pay for them . The number of Fog Counters they get depends on the number of " Cloudians " on the field when each " Cloudian " is Normal Summoned . Since they have many cards to quickly Summon Cloudians like " Cloudian - Sheep Cloud " and " Cloudian - Turbulence " , they can quickly swarm the field . The strength of the " Cloudians " lies in their ability to destroy cards using the Fog Counters , limiting the opponent ' s ability to respond . Fog Counters . These are the main power source for " Cloudian " monsters . These counters should be placed mainly on the " Cloudian " - player ' s monsters but certain " Cloudian " cards can take advantage of Fog Counter s anywhere on the field ( e . g . " Cloudian - Nimbusman " , " Diamond - Dust Cyclone " ) . " Cloudians " generally gain Fog Counters when they are Normal Summon ed . Since Fog Counters can only be placed on face - up monsters , " Light of Intervention " is a good card to use in a " Cloudian " Deck . A good way to gradually strengthen your monsters is to have " Cloudian Squall " out and stalling tools to buy turn s for accumulating Fog Counters . Recommended cards . " Cloudian " Decks are often underestimated because , while most of the " Cloudians " cannot be destroyed by battle while in Attack Position , if they are in Defense Position they are destroyed by their own effects . It wouldn ' t hurt to add a " Gozen Match " or " Rivalry of Warlords " in the Side Deck as nearly all the monsters are one Type and most of them are one Attribute . If you know what type of Deck your opponent uses , you could slip in one ( or both ) of the above cards to limit your opponent ' s Summoning abilities while leaving yours almost untouched . Another helpful card in a " Cloudian " Deck is " Mira the Star - Bearer " . Its effect protects your " Cloudian " monsters from being destroyed , and it ' s fairly simple to summon with " Cloudian - Turbulence " . If you choose to play " Athena " then a good card to use is " Valhalla , Hall of the Fallen " Weaknesses . While " Cloudians " cannot be destroyed by battle while in Attack Position , cards like " Stumbling " , " No Entry ! ! " , " Earthquake " , " Spider Web " and " Karakuri Shogun mdl 00 " Burei " " would cripple this Deck as the these cards all force monsters into Defense Position making the " Cloudians " destroy themselves . " Spiders " are also a threat for the same reason , since many of them change the Battle Positions of a monster to Defense Position . Effect - negation cards , like " Skill Drain " and " Angel O7 , " can make every " Cloudian " except " Eye of the Typhoon " über - fragile on the field . Without their effects or a significant offensive boost , all of the " Cloudians " save " Typhoon " are easily picked off by monsters with > 1800 ATK and many of them in this day and age can be easily Normal or Special Summoned . Their low ATK can also make them easy fodder for the " LV " " Armed Dragons " , " King Tiger Wanghu " and " Deck Destruction Virus " . " Savage Colosseum " combined with anti - attacking effects also gives trouble , because any " Cloudian " will be destroyed by " a card ' s effect " instead of " by battle " if any don ' t attack ; this can also be combined with " Begone , Knave ! " and " Des Counterblow " to not only remove them from the Field but also bump off Fog Counters ( this is especially an issue with " Nimbusman " . ) Speaking of Fog Counters , the archetype ' s main offensive cards ( " Nimbusman " , " Cirrostratus " , " Altus " , " Acid Cloud " and " Diamond Dust Cyclone " ) all rely on a steady supply of Counters to use their effects , making most " Cloudian " decks weak against " Exhausting Spell " and " Counter Cleaner . " Finally , since the majority of " Cloudian " s are WATER with meager stats , members of the archetype are easy targets for the effects of cards such as " Elemental HERO Inferno " or Diamond Dust . "
