The other Mono-colored deck strategies that have been flourishing in the current Standard format include the Mono-Green Aggro. Being a pilot of Stompy decks before during my early days on the Magic: the Gathering hobby, I can say that this deck got continuous support on every new Magic set released. In the recent Kaldheim set, Vorinclex, Monstrous Raider is the iconic creature that was included in the build, and the best decklist is added below.

The deck was piloted by Nemanja Kljajevic and finished in 1st place in The DWC Organizational VII @ The Disorganized Wizards Club.
