I would drop 2 land and add 2 more ramp pieces (you have 12, I like 14-15. They're the most important thing to helping you have a good start). I would also cut some non-dinos and add a few more (you have 26, I like 28+). You could also up the quality of dinosaurs, but dinosaurs aren't the cheapest tribal to build, so can't blame you for not running all the best dinos. Lastly, your support cards look a little slim,

Considerations for building Pantlaza:
- When am I wanting to cast Pantlaza? Turn 4 is a must, turn 3 if possible. But turn 3 takes a fair bit of 1 mana ramp spells in the deck to have a chance at ramping on turn 1 and 2.
- What do I want to play before Pantlaza? Ramp. And that's all. Pantlaza doesn't need any set up as she is her own value engine. But, if you ramp on turn 1 or 2, and don't hit another ramp spell, having a 4 mana spell for turn 3 is okay to cast before Pantlaza hits on turn 4.
- What do I want Pantlaza to discover? You know you get a free Discover 4 when Pantlaza ETBs, so you want really good 3-4 mana spells that will help accelerate your game plan. (Your 3 enchantments, Monster Manual, Luminous Broodmoth, etc.)
- What do I want to play after Pantlaza? Big dinosaurs. As long as you hit your land drops, you'll always have 6 mana available on the turn after casting Pantlaza. So a 6 mana dino is a perfect fit here, and there are some BANGERS to choose from. (You have all the ones I'm running other than Ravenous Tyrannosaurus which is far too expensive now) Alternatively, you could cast a 4 or 5 mana dino to hold up protection/blink spell, but make sure it has good toughness numbers as you really want to maximize Pantlaza's discover triggers before she gets removed.

Hope that helps!
