One of the casual formats that I enjoyed before when I was just starting on playing Magic TCG was Pauper and Peasant. For reference, Pauper is an all-commons format whereas Peasant only includes six uncommons and the rest are commons. It can also be played with the Standard-legal only cards. These format are usually played in demo games teaching those who want to learn the game, and I am planning to construct these decks for a future game demo activity. 
Anyhow, I was building some deck archetypes for a Facebook group named Mtg Peasants Bacolod as I wanted to contribute some ideas for their players. Here are the two decks I have come up so far:
