This was originally my most successful deck in Arena (until I discovered Merfolk).
I haven't found a specific deck archetype that it's weak against except decks based on pure speed. If my opponent is able to build a decent card advantage before I'm able to start getting the big baddies into play, I'm in for a rough match. That said, I've often been down under 10 life with my opponent having over 20 life before I've completely turned the tables on them.
What has made this deck so successful is that there is no single path to victory. There are a lot of ways to win. I find that the most important cards to get into play are:
Kinjalli's Caller and/or Knight of the Stampede, Kinjalli's Sunwing, and Temple Altisaur
The secondary cards from that point wind up being:
Forerunner of the Empire and Needletooth Raptor
I used to use Forerunner of the Empire's ability to search for a dino card to pull the Needletooth Raptor, but I now find that I typically use it to pull Gishath, Sun's Avatar.
The overall strategy is rather simple. Get Kinjalli's Caller or Knight of the Stampede onto the battlefield as soon as possible (the more, the better) to enable getting the big dinos out faster. Use Kinjalli's Sunwing, Shivan Fire, and Take Vengeance to slow your opponent down just enough...
Once you are able to get Temple Altisaur onto the battlefield and be able to attack/defend without using it, its usually just a matter of time before you have the match well in hand. From there, it really doesn't matter what big, bad dinos you play. They all start to really wreck things. I typically like to play Gishath, Sun's Avatar because of its ability to put multiple dinos from your library into play without paying mana cost. You rarely have to swing with it more than twice, and quite often only once.
