At the start of your turn, you will choose one of the three Houses within your deck and activate it. Once you have declared your active House, you may only play and use cards from that House, so be sure to choose wisely. Though you only can activate one House per turn, you’re free to use those cards as you please: no cards have a cost in KeyForge, so you can use your active House to run wild, playing and using cards without limit. At the end of your turn, you will draw back up to a full hand of six cards, so it may be best to play as many cards from your hand as possible. Then again, you may want to hold your best tricks back so you can get their full impact at the opportune moment! And that’s just the start of the tactical choices to make in every turn of KeyForge.
When you play creatures from your hand, you must build your team outward from the center, playing cards to the left and right of your creatures already on the field. But when you strike, you may attack with any of your creatures, regardless of their placement in your ranks. Once creatures are locked in combat, they match strength against strength, with each side dealing and taking damage.
