New one named Odd Squad just came out. Its on a Hero Academy like grid with various score and bonus tiles, and your units and items come from a deck of 50. You earn currency for wins and losses, and can buy packs of new units and items for your deck. Rather polished in some ways, but I cant see a way to chat, no rating system, and not visually as appealing as some (Hero Academy for example).
