One of the first things that I thought of after realizing that Final Fortune wasnt in the mix was to think of the other cards that might make sense to exploit
Many Commander staples (cards good in lots of decks) like Sol Ring or Arcane Signet are pretty cheap as singles (Sol Ring around $1.40, Arcane Signet $0.49)
With so much utility, its important to know which ramp spells are good for you
Given that the Shards of Alara storyline culminated with all the shards merging back into a single plane and the chaos and battles that ensued, we could have a cycle of shard invaders, misfits from their own original shard but who found a home in this new alien land
