The Beast slots in the game commonly consist of Harpies, Chimaera, and Prowler. As for the bottom three slots, players usually choose from Elemental, Unbound, Cycle, and Tank, selecting three out of these four options. The specific choice of cards to carry is left up to creative play, as the slots are all quite strong and can accommodate high-quality units. However, it’s important to consider how the top three slots complement your choices. If you prefer a straightforward option without too much strategizing, the Quilboar in the Cycle slot is a simple and viable choice.
