This is a cube that follows a strictly tringleton requirement. The goal is to balance and promote a handful of strategies that are/have been popular in modern legacy and vintage that are often not well supported in singleton cubes. The idea is to have these powerful decks with slight twists based on the limitations of the environment. Supported decks include

Delver
Vengevine/hollow one
Stage combo
Deaths shadow
Burn
Living end
Titan
Various aggressive land strategies

Fixing should be plentiful with a combination of fetches, triomes, shocks, and bounce lands.
