You're gonna have to be more specific than that. What EXACTLY is happening?

First strike does not work correctly. I have already seen in several games that it does not resolve damage correctly in different situations.
Both against creatures without first strike and against creatures with double strike

just played a game where the sword of anduril gave a creature either first strike or double strike even tho ive checked 5 times its not on the creature and not on the card unless the glitch is that it is there but not showing up it was a 1/1 token creature and i blocked with baral and karl zev which does have first strike so.... fix the **** plz and thank you. its not the first time this has happened.

defending shrine creature with toughness 2 against frist strike 5/2, both died :(

First Strike does not work. What are you guys doing?
