A - to - Z " A - to - Z " ( " ĒtuZi " ) is a series of LIGHT Machine monsters that are designed to fuse without any Fusion cards via Contact Fusion by banish ing the Fusion Material s from the field or , in the case of the Union monster s in the , from the Graveyard as well . They can also be powered up without fusing due to the fact that that most of them are Union monsters . These cards have been used by Seto Kaiba and Chazz Princeton . They are said to be rare cards in the " Yu - Gi - Oh ! GX " anime , as they are among the cards stolen by Vellian Crowler . This series is related to the " Armed Dragon " archetype ( which was a series until support cards were revealed in " " ) via " Armed Dragon Catapult Cannon " and the " Ojama " archetype via " Ojama Pajama " and " Ojamassimilation " , a reference to Chazz having played the three alongside each other during " Yu - Gi - Oh ! GX " . The Japanese lore of the anime - exclusive " Hyper Coat " specifies Machine monsters with " Ｖ " , " Ｗ " , " Ｘ " , " Ｙ " and / or " Ｚ " in their Japanese names , with the intention of supporting members of this series . Despite being called A - to - Z , this series lacks D - to - U monsters , with the anime - only " Dimensional Catapult " treated as the STU letters . General tips . " Ancient Fairy Dragon " can be used to Special Summon the pieces if they are in your hand , and " Summoner Monk , " " Shining Angel " , or " Jade Knight " can be used to search out three of the specific monsters necessary for assembling the more powerful Fusion Monster s . Also , since all of the archetype ' s key monsters are LIGHT attribute , " Saffira , Queen of Dragons " can be used to recycle them back to your hand or for extra draw power . By using the effects of " XYZ - Dragon Cannon " , " ABC - Dragon Buster " , and " A - to - Z - Dragon Buster Cannon " to constantly discard LIGHT monsters , " Saffira " will be able to constantly recycle one of them back to your hand during the End Phase of each turn , or draw more cards , making for a powerful and much needed draw engine in " A - to - Z " Decks , by allowing you to draw 2 cards during the End Phase of each and every turn . Basic Union Monster support Spell Cards are useful , such as " Frontline Base " and " Roll Out ! " . If you choose to include such cards , " Heavy Mech Support Platform " and " Heavy Mech Support Armor " provide more targets , and are useful when equipped to the fusion monsters , as it protects them from being targeted or destroyed by your opponent ' s cards . You can also equip the fusions with " A - Assault Core " , " B - Buster Drake " , and " C - Crush Wyvern " , summoned to the field at once via " Union Scramble " , and you will have a powerful monster that cannot be targeted by ( if it is equipped with " Heavy Mech Support Armor " ) and is unaffected by all your opponent ' s Spells , Traps , and monster effects ( if equipped with all three " ABC " Union monsters ) . If they are all equipped to " A - to - Z - Dragon Buster Cannon " , it is likely to keep a lot of pressure on your opponent during a duel since " A - to - Z " is a 4k beatstick that they will not be able to target with the likes of " Castel , the Skyblaster Musketeer " or " Dark Rebellion Xyz Dragon " , nor have their spells , traps , or effect monsters ' abilities work against it , that " also " has the ability to negate anything they attempt as long as its user has cards they are willing to discard . LIGHT - support spells in general also work , particularly " Honest " , seeing as it is both handy to protect the individual Union and Normal Monsters in addition to being a spectacularly effective way of paving a way to victory for the bigger Fusion Monsters , especially " A - to - Z - Dragon Buster Cannon " . A particularly devastating strategy is swarming the field with the base monsters , then using " Limiter Removal " to give them a huge rise in power just to finish the turn with fusing them together . " Dimension Explosion " can act as a sort of " De - Fusion " for these cards , only the targets to return to the field or Extra Deck are not limited to Fusion Monster - Fusion material relation . " Lightwave Tuning " , " Torque Tune Gear " , and " Chaos - End Master " are useful for any Synchro Summon s . " Unexpected Dai " is also a useful addition for the Deck , because it gives a means of searching " X - Head Cannon " and " V - Tiger Jet " that " Union Hangar " does not . Playing style . The " A - to - Z " cards are all about Unions . They are able to " combine " into the ultimate fighting machines , " VWXYZ - Dragon Catapult Cannon " , " ABC - Dragon Buster " , and " A - to - Z - Dragon Buster Cannon " ; all powerful forces , they are able to banish monsters , change battle positions , and even constantly negate the opponent ' s card effects in a manner similar to " Herald of Perfection " in the case of " A - to - Z - Dragon Buster Cannon " , making " Saffira , Queen of Dragons " a viable option for decks that include the ABC monsters and especially their respective Fusion Monsters . While " VWXYZ - Dragon Catapult Cannon " is powerful on your turn , it has no self protection , so adding cards to protect it would be wise , like " Ultimate Providence " . You can also use " Premature Return " , " D . D . R . - Different Dimension Reincarnation " or " Magnet Reverse " to re - summon this card . " Dimension Explosion " can help , especially when you can use it to help bring back monsters used for " XY - Dragon Cannon " , " YZ - Tank Dragon " , or " XZ - Tank Cannon " as alternatives to be able to Summon " XYZ - Dragon Cannon " . As three of the base cards are Union Monsters , Union support such as " Frontline Base " , " Union Hangar " , " Union Scramble " and " Roll Out ! " are viable options . " Morphtronic Scopen " is an ideal Tuner monster to use , as it can be Special Summoned through " Machine Assembly Line " , " Machina Armored Unit " and " Shining Angel " and can function as a Tuner of both Level s 3 and 4 . " Magnet Reverse " and " Chaos Hunter " work as counters to " System Down " without using " Imperial Iron Wall " , which would also prevent the Summon of this archetype ' s Fusion Monsters . XYZ Decks . Although " VWXYZ " has the ability to banish 1 card , the effect of " XYZ - Dragon Cannon " can be used multiple times in a single turn . Therefore , by removing " V - Tiger Jet " and " W - Wing Catapult " from your Deck and relying solely on " XYZ - Dragon Cannon " and " ABC - Dragon Buster " , you are left with more room to fill your Deck with other useful cards . By using a similar method to the one explained above you can create a Deck that can Special Summon " XYZ " and has Fusion Monster s that aren ' t so tough to get on to the field . The ABC Union monsters and " Heavy Mech Support Armor " can be used to protect your Fusion Monsters , " Power Tool " , or " Cyber Dragon " monsters from the negative effect of " Limiter Removal " without needing to worry about sacrificing Equip Spell Cards being used with " Power Tool Dragon " . Using cards like " Reckless Greed " ( carefully ) to draw cards to use as ' ammo ' for the effect of " XYZ - Dragon Cannon " is an effective way to clear the opponent ' s field . It is also good to play an " Overload Fusion " and " Cyber Dragon " for a " Chimeratech Overdragon " to put out enough ATK to finish you opponent off , or as a back - up plan if your " A - to - Z " monsters are destroyed . By the time you have an " XYZ - Dragon Cannon " on the field and used its effect to destroy your opponent ' s cards you should have enough monsters in your Graveyard to use " Overload Fusion " . Also , remember adding a few Synchro Monster s like " Karakuri Shogun mdl 00 " Burei " " and " Power Tool Dragon " ( equipped with Double Tool C & D ) to keep the opponent occupied until you can Summon an " XYZ - Dragon Cannon " . " D . D . R . - Different Dimension Reincarnation " , " Premature Return " and " Magnet Reverse " can also be used to re - summon your banished " XYZ - Dragon Cannon " or " ABC - Dragon Buster " that was used to summon this archetype ' s strongest monster ( " A - to - Z - Dragon Buster Cannon " ) , the latter being able to revive " ABC - Dragon Buster " from the Graveyard as well .
