While I am rooting for Red Green Dinosaurs or just purely Red Green Aggro to become a Tier 1 deck after the banning of Energy and Ramunap Red compo, looking for an updated decklist is probably the best first step. I have mentioned of a list before but with the metagame fully established, it is best to check on what are the recent improvements. One decklist I have found was from the Channel Fireball article for Deck of the Day. I have also checked on the GP Memphis and they had a deck referred to as Red Green Monsters which I think is that of RG Dinos. I have yet to verify though. Anyhow, here below is the decklist from CFB.
