"I accidentally made a murkrow that critical hits almost every attack"

I was playing BD and got myself a murkrow with super luck. Gave her a razor claw for giggles, and now she critical hits almost every single attack. What is the actual percentage/chance of her hitting critical now? I've been trying to figure it out by looking at the wikis but I've only found that super luck raises it by "1 stage", nothing about the razor claw and its ability increase. via /r/pokemon https://ift.tt/3IloRJ4
