That dinosaur is interesting. It's pretty unassuming, but the keywords and its p/t are very potent. I'm really surprised that they printed it. I guess people might play one or two of them in a dinosaur deck, where it will probably play the same role Reality Smasher does in Eldrazi decks.
Maybe you could also toss in a few of the Warrior tribal cards from Tarkit, since Neheb and a few other Minotaurs are also Warriors. And Lovisa Coldeyes. Also, there are also a lot of Shamans among them, so maybe Thornbite Staff?
I like the Gatewatch but I'm happy to hear this. I already feared that all mono-colored planeswalkers from now on would only be the core Gatewatch members which would have been boring. This allows more variance.
So when you cast this from yout hand and copy it while it's on the stack (for example, with Twincast, or, to stay in Standard, Insidious Will), you win instantly, since the copy resolves first? Neat. Additionally, this seems a nice splashable wincon in some Commander decks, where drawing seven cards can be very easy.
You cast copy from the hand? I don't think so.
Rise doesn't check that both casts were from the hand. I think the confusion here comes from "did it get cast if it was copied and the other spell doesn't use the word 'cast' in its text"
If it does... modern jankstack in Bant colors?
Yeah, already edited myself. It won't work since the copy wasn't cast at all.

Edit: ah no, the copy wasn't cast itself, so you won't win when the original resolves. Aw damn. Still a nice card.
What I like besides everything else that has already been said, is that they took an old, good card and varied it slightly such that it fills a different role. Nobody cares for an Eternal Witness once it is on the battlefield, but this guy? It deters big beaters for days (actually, while writing, I noticed that I should put it in my Atraxa Planeswalker deck ). I wished that they printed creatures like this more often, like a Duplicant with Trample, a Burning-Tree Emissary with Double Strike, a Snapcaster Mage with Prowess, a Solemn Simulacrum with Graft, a Farhaven Elf with Indestructible, a Recruiter of the Guard with protection from monocolored... of course, each with a certain drawback. You get the idea.
I think it would make games much more interesting: Instead of cluttering the the battlefield with otherwise useless chump blockers, you'd have to play around the creatures' drawbacks, while gaining advantage in other areas, rewarding you for good plays. These value creatures might even give aggro decks an edge, since they'd be able to play creatures that are efficient in combat while still providing some immediate value, something those decks severly lack in Commander.
