# Deck Structure

Decks will need to have at least 40 cards, from which a maximum of 5 god tier units and 5 hero units will be allowed. Larger decks will give the player more cards to spare before losing by deck depletion but drawing gods or heroes will be significantly rarer. Starting hands will have 5 cards, for a maximum of 8 at all times.
