Hunder " hunder " , known as " Thunder " ( サンダー , " Sandā " ) in the " Yu - Gi - Oh ! ZEXAL " manga , is an archetype used by Thunder Spark . It is composed of Level 4 Thunder monsters whose names are puns that indicate members of a family . The archetype is solely supported by " Otonari Thunder " . The names in Japan were originally based on a pun involving their phonetic spelling . This pun used the first three letters of their names in relation to the Japanese honorifics : Oto - san , Oka - san , One - san , and Onii - san . Their English equivalents are Father , Mother , Sister and Brother respectively . Play style . This archetype ' s focus is to Normal Summon multiple Level 4 LIGHT Thunder type monsters in one turn to Xyz Summon Rank 4 monsters such as " " . Then , you can continue using their effects by replenishing Xyz Material s using " Spirit Converter " , which allows you to attach one Level 4 LIGHT monster as an Xyz Material to an Xyz Monster on the field . This means that you can reuse monster effects like the attack negation of " " , or the second effect of " Number 91 : Thunder Spark Dragon " . There are two common playing styles to this archetype - - Control and Swarm . For the Swarm strategy , because of the abilities of Mahunder and Pahunder , you can perform multiple Normal Summons to land large amounts of damage on your opponent provided all of your monsters attack directly . This can be improved by Solidarity ; however , be aware there are no Thunder - Type Xyz monsters that can be supported by this archetype at this time , and thus if you Xyz Summon , you may cause Solidarity ' s effect to become null . You can use Dimensional Fissure to help evade this , as the Xyz Materials will go to the Graveyard , but the Xyz Monster ( s ) will be Banished . You can also use Scrap Dragon ( if your deck runs Vylon Prism ) and destroy the now - useless Spell card if necessary . For the Control strategy , you ' d want to focus on dropping 1 Xyz at a time ( such as Starliege Paladynamo or Constellar Omega ) for your opponent to be pressured by , while maintaining a powerful hand advantage by using Thunder Seahorse , Sishunder and Recycling Batteries . Support your Xyz monster with cards such as Kaiser Colosseum , Effect Veiler , Honest , and other various Spells , Traps , and Effect Monsters . Then during the next turn , play another Xyz Monster to either regain , maintain , or further improve your advantage . Using Tragoedia in this strategy is a great defense mechanism that can turn into a powerful offense , as you can generally keep a large hand consisting of 4 or more cards consistently . Because this archetype has such flexibility , you can take portions of both strategies and implement them into a single deck . You can use control cards in a swarm strategy to keep your opponent from countering you ; you can Summon multiple monsters at once in a control strategy to inflict the final blow to your opponent after you ' ve countered all of their other options . In addition , because of the numerous Level 4 LIGHT Thunder - Types that currently exist , you can take this deck and create multiple hybrids - - Batteryman Hunders ( Batteryman AAA and Batteryman 9 - Volt ) , Watt Hunders ( Wattcobra , Wattgiraffe , and Wattpheasant ) , or even Elemental HERO Hunders ( Elemental HERO Voltic ) . An easy way to incorporate Synchro Summoning into this archetype is to run the Tuner monster Vylon Prism , due to its ability of being added to your hand by Thunder Sea Horse and is summonable by Pahunder and Mahunder .
