So, red has burn deck via burn spells, black have burn deck via drain spells, blue have Psionic Blast, Parasitic Strix, and maybe Vapor Snag and Psychic Barrier, and white can cast Summary Judgment on their own Boros Reckoner and Phyrexian Vindicator... but what about green?
Green has Hornet Sting and Unyaro Bees, but burning your opponent to death with them will be a mighty challenge... But then I found our card of the day: Biorhythm! It doesn't say "deal damage" but if black deck that use spells like card:sovereign's bites can be said as a burn, then maybe this can as well? Setting a life to a lower amount causes loss of life, after all.
But Biorhythm is expensive: It costs a whopping eight mana! So maybe we put it in a Mono-Green Tron shell? Swapping out their usual wincons like Ulamog, the Ceaseless Hunger and Ugin, the Spirit Dragon with Biorhythm, bringing in more boardwipe in the form of Nevinyrral's Disk to accompany Oblivion Stone so opponent would have no creature when you cast Biorhythm, and Darksteel Myr to accompany Wurmcoil Engine so after you activate Disk or Stone you still have creatures on the battlefield to not die when you cast Biorhythm......
I only made this deck just now, but the idea seems kinda legit right? The preliminary testing seems promising, altho I haven't played a normal Mono-Green Tron to have the experience to compare it to.
Also I accidentally made the deck have 20 lands when they usually have 18. Maybe you can swap out a Boseiju and a Yavimaya for something else, idk.
