Frog Monarch Frog Monarchs , also known as Frognarchs , Frogarchs , or Froggy Monarchs is a Deck type , which combines " Frog " and " Monarch " monsters . The idea of the Deck is to use " Treeborn Frog " , " Swap Frog " and " Ronintoadin " to make tribute fodder . Another purpose of " Swap Frog " is to send " Treeborn Frog " or " Ronintoadin " to the Graveyard and to return " Monarchs " to hand for later use . This Deck creates enough tribute fodder for duelists to have up to 15 monsters that require Tribute Summon ing , while still managing to play smoothly . One can even take advantage of all the tribute based " spell " and " Frog " cards and try to pack a three tribute monster like " Beast King Barbaros " or " Destiny HERO - Plasma " . The September 2010 Lists slowed the deck down , thanks to " Substitoad " going straight from Unlimited to Forbidden . While there are still plenty of ways to search and dump " Treeborn Frog " into the graveyard , Frognarch players no longer enjoy the considerable deck - thinning abilities and easy " Dupe Frog " locks that " Substitoad " provided . However , the addition of " Formula Synchron " and the ease of which it can be summoned via " Treeborn Frog " plus " Fishborg Blaster " have helped offset the loss a bit . Due to the banning of Fishborg Blaster , Effect Veiler has been added commonly to the deck as a replacement tuner for Formula Synchron , and is also versatile because it can negate effects that begin OTK s . Originally , this decktype rarely included Synchro Monster s , instead focusing solely on creating tribute fodder for the large numbers of tribute monsters they ran ; but the aforementioned release of " Formula Synchron " and banning of " Substitoad " have resulted in the rise of an offshoot ( typically referred to as " Formula Monarchs " ) of this deck that relies more heavily on Synchro Monsters . However , the September 2011 Lists has essentially rendered the synchro - orientated decks unplayable with the limitation of Formula Synchron , Pot of Avarice , and especially the ban of Fishborg Blaster , Formula Monarchs signature Tuner monster . Mass Tribute . The idea of this deck is to Tribute Summon the " Monarch s " by using the " Frog " Monsters ' ability to swarm the field with monsters when necessary . Thanks to " Treeborn Frog ' s " ability to come back to the field every turn , you don ' t have to worry about the Tribute materials for the " Monarch s " . In order to use " Treeborn Frog ' s " strategy , the deck uses loads of cards that will help you get it into the Graveyard such as " One for One " , " Foolish Burial " , " Genex Undine " , and " Swap Frog " . Another strategy that can lead to clearing of the opponent ' s field and more fodder would be the use of " Enemy Controller " . Because this card is a Quick - Play Spell Card , it can tribute " Treeborn Frog " during your Standby Phase after its summon , while still giving you the opportunity to summon it again . With the help of cards such as " Level Eater " and " Ronintoadin " , Tribute Summoning cards that requires multiple Tribute Materials ( such as " Egyptian God s " or " Beast King Barbaros " ) is very easy to preform . It is risky to use any Trap Cards in this deck as you will be unable to revive " Treeborn Frog " . Occasionally , one " Treacherous Trap Hole " is used , because it can be activated at any time , or chainable Draw Power , such as " Legacy of Yata - Garasu " and " Jar of Greed " ) , because you can activate it before or during your Standby Phase . Formula Monarchs . The Formula Monarch deck is based on the old Frognarch deck , adding 1 - 2 copies of " Fishborg Blaster " to Synchro Summon with " Treeborn Frog " to make " Formula Synchron " every turn . You cannot send " Fishborg Blaster " to your Graveyard for " Swap Frog " s effect as " Fishborg " is not an Aqua - Type monster . Ideally , you can discard " Fishborg Blaster " and Special Summon " Swap Frog " from your hand , then use its effect to send " Treeborn Frog " to the Graveyard ; but you ' re not always going to have both " Swap Frog " and " Fishborg Blaster " in your hand to start with . Because of that , a lot of players add " Genex Undine " ( and , by extension , " Genex Controller " ) , which can send " any " WATER monster to the Graveyard . You can then use the " Genex Controller " you added to your hand as discard fodder for " Fishborg " , or you can even summon it on a later turn for a Synchro Summon ( you can tune it with " Caius the Shadow Monarch " to make " Locomotion R - Genex " ) . Weaknesses . Frog Monarchs , whilst being a very control - oriented deck , do have several weaknesses , the first and most obvious being heavy reliance on tribute monsters which creates dependencies ( leading to potentially bad hands ) and makes it a dangerously slow archetype in the current fast paced metagame . " Zombie World " and " Mask of Restrict " — both of which will prevent Tribute Summons — can be extremely deadly if the Monarch player finds themselves with a hand full of tribute monsters and no spell / trap removal . Perhaps even worse than the above are cards that lock out Special Summons entirely ; like " Archlord Kristya " , " Vanity ' s Fiend " , and " Fossil Dyna Pachycephalo " , which will shut down a " Monarch " deck completely until they can draw something like " Soul Exchange " , " Dark Hole " , or " Treacherous Trap Hole " to get rid of the threat . Another weakness of the deck ' s main build is its requirement to have " Treeborn Frog " in the Graveyard . Cards that Banish monster such as " D . D . Crow " and " Chain Disappearance " work extremely well at neutralizing " Treeborn Frog " . " Trap Stun " can neutralize most of these threats , but it ' s a good idea to have " Burial from a Different Dimension " as a backup . As for the general play style of Frognarchs : even with the assistance of cards like " One for One " and " Formula Synchron " it ' s still a relatively slow deck . A deck with swift speed that can create a strong field presence can usually hold its own against this deck . Alternatively , a deck that can consistently prevent the " Monarch " player from gaining field presence will also do quite well against them . Particularly difficult matchups for " Monarchs " in this respect are " Gladiator Beast s " ( especially due to " Gladiator Beast Retiari " ) and " Machina Gadget s " ( due to " Machina Fortress " , whose effect allows them to gain advantage in exchange for " Monarch ' s " effects ) . Also , since Monarchs are the main monsters of the deck , Intercept can easily prevent the deck from gaining field presence .
