This version of dinosaurs is something that I have been mulling around with. The Gruul version that I have been playing with puts a lot of inevitability, however, compared to Red, B/W/x control decks it seems like it is too slow especially on the draw or if you miss mana dorks/land drops. I find one weakness with the G/R version is that if you kill the dorks early more often than not the deck is slowed just enough to overtake or to at least stalemate the board. This list might not be competitive at all, but at the same time, it is looking at the dinosaur archetype at a different angle.
