This is a vintage cube designed with the intention of maximizing fun, interaction and value. The goal is to have highly synergistic and flexible options to allow the player to chase after a variety of exciting decks, while ensuring that most of the "value engines" are easy to interact with so that no matter the matchup it feels like both players have a chance. While there are a few two card game-winning combos, the major focus was on creating value engines and 3+ card combos. This means aligning cards that play very well together but don't necessarily win, which I find more fun and lead to more interactive games as well as great comeback stories (staring down an opponent with Gitrog monster and seismic assault in play with life from the loam in their graveyard certainly isn't a great position to be in, but it is possible to beat and a lot more interesting/fun than a reanmiated Iona).

Many of the archetypes are obvious, but I'll explain some of the more exotic builds here.

Second sunrise/Faith's reward: These cards are a lot better than they might seem. There are quite a few cheap artifacts floating around (chromatic star/sphere/lotus bloom/ black lotus etc), as well as cards like squandered resources, sylvan safekeeper and ghost quarter to destroy your own lands as needed. You can even use Greater Gargadon or Thopter foundry as sac outlets if you really want to go deep (imagine sacrificing something like coveted jewel and returning it to the battlefield!). You can also loop second sunrise by playing archeomancer or eternal witness, killing them (with something like a spellbomb or executioner's capsule) and getting back the sunrise for an infinite combo. An easy card to start off a combo with is Transmute artifact, which can do something like sacrifice a gilded lotus, find a lotus bloom and start the combo loops. There are plenty more ways you can make these cards work, I'm just excited to see what creative combos you come up with.

With all the cheap artifacts, Auriok salvagers is an easy inclusion. It gets infinite mana with either LED or black lotus for a combo kill, but can also just provide repeatable value getting back a pyrite spellbomb or mishra's bauble.

The same goes for Glissa the traitor. One of my pet cards and criminally underrated, Glissa can really go deep with the likes of walking ballista, executioner's capsule, ratchet bomb, engineered explosives while also being really fun if you're lucky enough to have a black lotus.

Legendary Creatures: There are TONS of legends in this cube. Part of that is to facilitate mox amber as a playable inclusion, the other is to create a 5 color legends archetype. The main staples of this build are Captain Sisay, Esika, God of the tree, Jegantha the Wellspring and the fun 5 color cards like niv-mizzet reborn. (Activating Sisay to find Niv-Mizzet is a particularly fun value play). This archetype is highly accelerated by prophet of kruphix or birthing pod, and is complemented by the numerous Saffi Eriksdotter/Reveillark, Teshar, Heliod combos.

Custom Cards: There are some cards that I really enjoy, but unfortunately are just not quite at the rate for vintage cube play. So I have modified their casting costs to make them viable in this higher power environment. The first is seismic assault, which I changed to cost RG. I think this casting cost better signals the archetype, is a draw into those colors and is a lot easier to cast. The other card is goblin bombardment, which I made colorless to allow white, green and black decks to take better advantage of the effect. This prevents the sacrifice deck from being solidly spread across 4 colors (there are a lot of GW combos involving revilark, Teshar and Saffi which benefit from this greatly, as well as mono black zombies lists that are overloaded with black mana costs so splashing can be difficult). I also added a custom card for doom foretold.
