Emperor is played with 3 player teams.
Emperor sits in the middle and he’s generals on both sides of the Emperor
Emperors have range of influence of 2 so since the beginning of the game they can affect only till the opposing generals. Generals have range of 1 so in the beginning they can only affect the general directly in front of him.
Players play separately so no shared life totals, libraries or anything but it is possible to deploy creatures, giving each creature the following ability “{T}: Target teammate gains control of this creature. Play this ability only any time you could play a sorcery.” If a player is eliminated from the game so is all their cards, so you a general about to go down can’t leave his army to Emperor but they will disappear with the dying general.
You only win as a team if the opposing general is defeated.
