Might I suggest Infernal Plunge and Culling the Weak to give ramp and sacrifice for value? Alternately, if you do want to keep in a bunch of color, you might be better served by Kaleidostone, and Geothermal Crevice over Prismatic Lens and Jund Panorama. Sunburst might also be a good mechanic to consider. In particular, Opaline Bracers could go well with the cheap flyers, Pentad Prism could help you fix for a turn 4 Dragonsoul Knight attack, and Skyreach Manta could act as psuedo knights. Also, if you go Jund, Commune with Nature and Commune with the Gods are options to help you find pieces, and Bloodbriar from the most recent set could be quite powerful in this deck. You're running so many mana fixers, I don't see any reason not to splash a third color.

Oh, also, if you decide to go hard with two colors, getting a big payoff for the tribal theme such as Aphetto Dredging or Distant Melody should be at the top of your list. If you decide to get a payoff for going 5-color, Domain cards like Tribal Flames or Matca Rioters are powerful options. You could even go jund, as I mentioned above, and put together an enchantment package that uses Commune with the Gods to search up dragons or things like Exotic Curse (Domain!), Boon of Emrakul/Sangrite Backlash, Clinging Darkness, Dead Weight, Stab Wound.

cipher only triggers on combat damage, not any damage. Fyi :)

Crap, lol. I actually hadn't realized there was a difference in the damage types. For this deck I can just put the midnight recoverys on the dragon hatchling instead, but I'll need to check my other decks to make sure I didn't make this error elsewhere. Thanks for the FYI :) SocksofGranduer
