The Toad series is a related series of monsters that support the "Frog" archetype.
"Froggy Forcefield" is not a "Frog" card, because it does not have 「ガエル」 in its Japanese name. "Slime Toad", previously known as "Frog the Jam", is also not a "Frog" card because of its Japanese name, and was renamed to clarify this.
In Italian and Spanish, since November 2016, the archetype name is capitalized as "RANA". This prevents the archetype name clashing with other archetype names in those languages, such as "Ancient Gear" ("Ingranaggio Antico" in Italian). This is similar to how the "LV" and "HERO" archetypes are capitalized in all TCG languages.
True to their their name, the "Frog" as well as the related Toad monsters resemble their real-life counterparts. Some "Frog" monsters like "Flip Flop Frog" and "Poison Draw Frog" showcase their long, sticky tongues in their artwork. Most of the "Frog" and Toad monsters have distinctive colorful markings on their bodies and heads, most notably "Swap Frog", "Dupe Frog", "Beelze Frog", and "Ronintoadin".
Some "Frog" and Toad monsters resemble angels like "Amphibian Angel - Frog-Hael" and "Treeborn Frog, while others resemble demons like "Beelze Frog" and "Swap Frog". This thematic resemblance to angels and demons is further highlighted by the contrasting half-angel, half-demon appearances of "Substitoad" and "Tradetoad".
All members of the "Frog" (ガエル Gaeru) archetype, as well as members of the Toad (カエル Kaeru) series (which support the "Frog" archetype), integrate puns into their Japanese names. While both Gaeru and Kaeru mean "Frog" in Japanese, the latter is translated as Toad in the TCG in order to distinguish the different words. "T.A.D.P.O.L.E.", a monster related to the "Frog" archetype, also has a pun on its Japanese name.
The puns in their names mostly rely on the fact that the interchangeable Japanes words Gaeru (ガエル) and Kaeru (カエル) are homonymous with the plain form conjugation of some Japanese verbs. These puns were not retained in the TCG names, if not replaced by different ones, since they are mostly untranslateable.
Though weak, "Frog" cards can unleash devastating effects that include rapid Summoning, the option to increase their ATK or protect themselves from destruction, and wiping out all cards the opponent controls. Many "Frog" cards have low Levels, which lets them benefit from cards like "Gravity Bind", "Pride of the Weak" and "Graceful Revival".
Frog Decks benefit the most from the use the Field Spell "Wetlands" that increases the ATK of all Level 2 or lower WATER/Aqua Monsters by 1200. The goal of a Wetlands Beatdown Deck is usually to provide an early game beatdown and then lock down an increasingly defensive opponent through cards like "Gravity Bind", a Double "Dupe Frog" Lock, or the effect of "Cryomancer of the Ice Barrier". "Dewdark of the Ice Barrier" works with "Unifrog" with their ability to attack directly. "Flip Flop Frog" can be set up during a lockdown to clear the opponent's field and get an OTK.
This Deck type uses the "Frog" monsters as an engine for the "Monarch" monsters. The idea of this Deck is to use "Treeborn Frog", "Swap Frog" and "Ronintoadin" to generate 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. "Swap Frog" can also be used to abuse the effect of "Raiza the Storm Monarch" by returning it to the hand and reusing it to continually return a card controlled by the opponent to the top of their Deck, preventing them from drawing new cards.
"Toadally Awesome" is a very powerful Toad monster that has an effect that can negate the activation of any Spell/Trap Card or monster effect, then Set that card on the activator's field. A well-structured usage of "Ronintoadin" and "Swap Frog" can easily swarm the field and grave with Level 2 monsters to either Summon "Toadally Awesome" or be used as fodder for it. Aditionally, "Toadally Awesome" can special summon "Frog" monsters directly from the deck, further increasing the Deck's consistency.
This Deck uses the Toad monster "Ronintoadin" to summon itself by banishing Frog monsters in the graveyard, while "Sea Lancer" takes advantage of those banished Frog monsters by using them as equip cards. This method effectively recycles banished Frog monsters, which can potentially be reused by "Ronintoadin. "Toadally Awesome" can be brought out frequently with this Deck being able to Summon Level 2 Aqua monsters very quickly. It is recommended to use both "Dupe Frog" and "Poison Draw Frog" because both get their effects when they are sent as "Sea Lancer's" equip card to the Graveyard.
Basically, the central strategy of this deck and win in a single turn by destroying all cards on the opponent’s field by using "Des Croaking" and subsequently delivering the finishing blow by attacking with all three "Des Frog"s. As a central requirement for the use of "Des Croaking", there must be at least three "Des Frog"s on the field, which can be accomplished easily either by Tribute Summoning “Des Frog” and using its own effect, or through the use of "Inferno Reckless Summon" as a tech card.
This Deck abuses the effect of the Toad monster "Ronintoadin" to continously summon itself from the graveyard as a fodder for the effect of "Mass Driver", "Cannon Soldier", or a card with the effect that tributes monsters to inflict direct damage to the opponent's life points ("Catapult Turtle" will not work because "Ronintoadin"'s attack is far too low). This "First Turn Kill" strategy involves the key card "Substitoad" to fill the graveyard with enough "Frog" monsters that will be used by "Ronintoadin" to fuel its own effect.
Once the necessary cards are set, this FTK is hard to stop, and relatively easy to accomplish. Once "Substitoad" is on the field (easy with "One for One" or "Swap Frog" + "Salvage") with another monster, the graveyard can be easily filled with as many "Frog" monsters as possible. "Swap Frog" can easily send "Ronintoadin" to the graveyard once summoned with the effect of "Substitoad". By the time that the graveyard is ready, "Mass Driver" is used to tribute a "Ronintoadin" to inflict direct damage to the ooponent. Since "Ronintoadin" can continously revive itself, "Mass Driver" can repeat the process until the opponent's LP hits 0. A "Cannon Soldier" or its Toon counterpart "Toon Cannon Soldier" (searchable by "Toon Table of Contents") can be used instead of a "Mass Driver", but since it has to be summoned to the field first, "Double Summon" will be very useful.
With the banning of "Substitoad" in September 2010 and "Mass Driver" in March 2011, this classic strategy is no longer playable in the Advanced Format.
The strategy of this classic deck is use the effect of the Toad monster "Substitoad" to continously send Frog monsters from the field to the graveyard while the latter is affacted with and effect that Changes Type such as "DNA Surgery" and "D. Tribe", and finally use the effect of "Super Rejuvenation" to draw through the rest of the Deck during the End Phase and cause a win condition using the 5 parts of "Exodia".
