Truly, this has got to be in top three for the Most Frequently Asked Questions.
If attack is the same, Lower stars win. EG. If I have Lehane at 40 attack and you have Tyd at 40 attack, I'd win because of having 2 stars to your 3.
If attack and stars are both the same, attacker wins. EG. If you played Bob Joby to 3 attack with bonus, and I'd play a Spiaghi at the starting pill so I would get 3 attack, You'd win because of going first.
There was a thread on this already but i cant find it basically if u have the same atk the card with the lower star count wins if youll have the same atk and same stars then the person who was played first in the round will win UNLESS U ARE PLAYING ON RANDOM
