Three bonus attacks

It's really messed up that I can be winning for an entire game and then a plant hero player plays the card that does 3 bonus attacks and wins the game. The card is super o.p and I think it should be removed from the game. I can't tell you how many games I've lost because of that card.  I just lost a game where my hero hadn't been hit the entire game and the plant hero had no shield left because I hit them so many times and then they played the 3 bonus attacks card and win.  At least reduce it to two bonus attacks. Ive noticed several changes to the game lately and that should be another one.
