Halo Fountain Halo Fountain is a 3-mana artifact from Streets of New Capenna that creates tokens, draws cards, and even offers an alternative win condition
It features a full cycle of on-color indestructible lands as well as bounce lands (allowing you to replay lands after remaining lands are destroyed), as well as a ton of mana rocks that will survive past your Armageddon effects
For example, if you control Twins of Discord and a colorless creature with bloodthirst 1 enters the battlefield under your control, that creature will enter the battlefield with three +1/+1 counters on it if an opponent has been dealt damage that turn
Ill give the Simic commander credit, though
Pyxis of Pandemonium is a repeatable way to exile the top card of my library, but it can also serve a very important role
Staying Power I tried to get variations of this card into three different normal sets
