Mirror force
Once again just as yesterdays cotd was a staple now this is not just a staple it is probably one of the best cards in the game this is 99.9% of the time 1# on a persons top ten list this is my favorite card and this is even better than riageki because you can get the full use. Now here is a scenario your opponent has 2 monsters on their side of the field and you have none for some reason (riageki their mirror force) And you have 400 lp left and they summon a 3rd monster and you previously set a mirror force. They attack you kill all of there monster if you had used riageki you would have lost any ways this is what makes it better than that card. This belongs in every deck 5/5
