Mine was written up in my feature match round 5 against Corey. I have Perdition's Blade (not exhausted), Eye of Rend, and Striker's Mark on the table (that's a 4 atk P Blade for those counting). In addition to those, I had a Skibi's Pendant which would've let my P Blade swing for free. Corey drops a Moko and runs him into me. With no resources ready, I took the 5 damage and let Moko live. It wasn't until the next Moko came out that I realized I could've taken the first one out for free!
