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 Summoning, 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".
