Blitz
From Halopedia, the Halo wiki
Blitz is a gametype introduced in Halo Wars 2. The game revolves around the use of cards that can deploy units or abilities onto the battlefield at the expense of energy.
For a list of the cards available in Blitz, see List of Blitz cards.
Players enter the game with a deck that consists of a leader and 12 cards, where you will have 4 cards in one hand at all times. After deploying a card, a new card will takes it's place. After cycling through all other cards players will draw this card again and be able to use it. Energy is scattered throughout the map and requires players to find and collect. Spawning units not only costs energy, but there is also a health penalty for spawning units outside a player's home base. A variant of the gametype called Blitz Firefight also exists.
