How do you make a frog deck?

Answer 1

Frog decks uses the Field Spell Wetlands that will increase the ATK of all level 2 or lower Water Aqua monsters by 1200. You can use T.A.D.P.O.L.E. (Which will also give you 2 more) or stalling Frog cards like Substitoad along with Dupe Frog or Flip Flop Frog and Treeborn Frog to defend in order to build up combos. For example, T.A.D.P.O.L.E.s can power up your Beelze Frogs to 2100 ATK, a pretty high attack for a level three monster. Since Frogs are all low- level, you can use cards that benefit from this, like Pride of the Weak or Graceful Revival.

Also remember that Frogs have an unlimited amount of monster milling due to Substitoad.

Big Wave Small Wave can be useful for bringing out Des Frog form your hand. Water Hazard is another powerful Spell that can allows you to Special Summon frogs from your hand.
