Rivals of Ixalan Prerelease (Limited)

Rivals of Ixalan Prerelease.
Went 2-2. All matches went to 3 games.

For my deck, it was pretty much all about surviving long enough to play 'Zetalpa, Primal Dawn'

My promo was Zetalpa -- and that made the choice to play dinosaurs pretty easy.
Changes I would/should have made...
+1 Forest / -1 Mountain
+1 Mutiny / -1 Relentless Raptor

Relentless raptor works better in just a two color deck.
Don't play it in a 3 color deck -- even if you having mana fixing.
It's a card you want to play early. That tends not to work well in 3 color with mana fixing.
During the prerelease, I was just thinking 3/3 Vigilance for 2 mana -- cool,
but it really didn't make it into play when it was relevant.

I was initially playing mutiny instead of Firecannon Blast, then swapped out mutiny for blast.
I think the right move would have been playing both.
Cutting Relentless Raptor for Mutiny seems reasonable.

The Immortal Sun was tempting to swap out when facing a deck without a planeswalker, but I think you need to keep it in at all times. It's a pretty good bomb, especially with dinos... which are already big.

Stampeding Horncrest is decent (if expensive), would have liked to have found room for it... but I'm not sure what to swap out for it.
