IT is pretty hard to understand though because you only see the end result of each round without seeing what cards were played, so if I lightening a creature, it leaves you guessing what happened.
Furthermore, new cards are not included at all making it extra confusing.
I think everyone wishes this was at least updated.
Frankly I wish the whole game was real time. IE you see each spell played when it is played, rather than seeing a saved log repeated after it already happened. But that might be too much work and too abusable. Don't know but it would be nice.
