RIX Cards to add:
- Forerunner of the Empire (4 of: 4 mana, tutors dinos, and may rile everybody)
- Side deck Blood Sun, vs decks with a lot of non-basic lands
- Needletooth Raptor
- Shake the Foundations also riles everybody, with replacement
- Enter the Unknown (green ramp)
- Ghalta, Primal Hunger (a big MF dinosaur)
- Polyraptor (8 mana "I win" card)
- Zacama, Primal Calamity: (9 mana Naya "I win" card)
- Consider Raging Regisaur as an alternative to Raging Swordtooth and/or Regisaur Alpha, especially if I need to move my mana curve from 5 to 4.
- Splashing white for Sun Crested Pterodon would help me vs flying, although it's a 5-mana card.

Honestly, this deck really wants to be Green/Red, not Green, Red, White.  Bellowing Aegisaur is a killer in this deck, though.

Things that this deck can't handle:
- Burn spells to the heads.

The obvious problem with this deck currently (besides no solutions for fliers) is that it needs more control in order to last until turn 5+ when the combo starts to fire. Partially fixed: Heaven//Earth does everything I want!

Needs more Ramp.

I just had a wicked thought: Raptor Hatchling spawns dinosaurs on damage, not on death.  If I buffed Raptor Hatchling up with one or two +1/+1 counters, I could hit him to generate a new 3/3 dino each turn!
