First,
Manabond is banned.
Now, as to the engines involved:
Crucible of Worlds/
Life from the loam allow you to sacrifice/discard lands without caring
Glacial Chasm/
Constant mists let you
fog your opponents for days
Grove of the burnwillows +
punishing fire lets you net one damage every turn
Wasteland/ghostquarter lets you kill their manabase
Darkdepths + Thespian stage gets you a Merit late token for two land and two mana (copy the depths with stage, sac depth to legend rule, sac stage for a token because it has no counters)
Lots of mana + any x damage spell kills people
Look up my Tiny Sasaya deck for a mono-green deck that's similar, but more budget, and more resilient to removal
