Red is one of the best, and having access to green gives you the ability to ramp and help fix your colors so you are always able to cast your spells
Where possible, card draw and ramp has been concentrated in Auras and Equipment also, in order to give us a better chance at triggering Chishiro
While fetch lands and shock lands are out of reach, a combination of guildgates, common tap-lands (like Scoured Barrens), and bounce lands (like Simic Growth Chamber) can create a surprisingly consistent foundation
This damage can be split up between up to eight targets, though, so you can easily wipe out a couple of your opponent's creatures with this ability alone
I was recently playing a game of Commander with my wife, and these would have been perfect for just that occasion rather than pitting Lorehold Spirit against Food & Fellowship
