Pirates, Dinosaurs & Treasure
It appears that someone at WotC headquarters got a bit overzealous and sent out notifications for upcoming cards a bit early.

In addition to some new Ixalan cards, they also shared some of the new Tokens we will be seeing in the set:

3/3 Dinosaur w/ Trample

2/2 Pirate w/ Menace

Treasure

The August Tokens have already been ordered, but I am already hard at work looking for next month's Tokens.

Pirates, Dinosaurs, and Treasure, Oh my!
