This is a basic frog deck that is fast and has more than one strategy. Swap Frog is one of the most important cards in this deck as is Substitoad and Dupe Frog. Its main strength is it is constantly flexible and you can almost always have any monster you need to hand. It is also very fast with it's ability to special summon and gain an extra normal summon with Swap Frog.
3x Des Frog
3x Dupe Frog
3x Submarine Frog
3x Swap Frog
2x Flip Flop Frog
Swords of Revealing Light
Level Limit Area B
2x Des Croaking
Mystical Space Typhoon
2x Dark Bribe
2x Aegis of the Ocean Dragon Lord
2x Froggy Forcefield
This Deck uses Swap Frogs effect to send the two T.A.D.P.O.L.E's to the graveyard as fast as possible. Using his return to the hand and special summoning abilities you can sacrifice him for Des Frog, activate Des Croaking and attack. If this is not possible then another tactic is sending monsters from the deck to the graveyard with Swap Frog's effect and bring them to the hand using Salvage.
Another strategy involves Wetlands. Using Swap Frog's effect to special summon and gain extra summons you can quickly fill the field. Once you have a few monsters protect them with Aegis of the Ocean Dragon Lord and Froggy Forcefield until you can get Substitoad. Using Substitoads effect bring out Submarine Frogs and a Flip Flop Frog. Flip Flop Frog can repeatedly bounce your opponents monsters to their hand and the Submarine Frogs use their high attack to strike directly.
If all else fails use Substitoad and Dupe Frog together so you cannot be attacked. If Dupe Frog is then killed you can add any Frog monster from your Deck or Graveyard to your hand. This keeps options open and using Dupe Frog and Substitoad you can almost always have whatever monster you need to hand.
If you have Level Limit Area B on the field and have a Substitoad and also have the ability to summon three Des Frog then do so and activate Des Croaking. This will clear the field and then use Substitoad's effect to destroy them and special summon the most powerful monsters possible afterwards. You can then use them to attack directly.
