When playing against Sparky, my Azure Beastbinder attacks and targets the mono-black deck's "Malakir Cullblade" and instead of turning it into a textless 2/2, it actually adds a +1/+1 counter to the creature (=the Cullblade). It's a minor bug that has no bearing on Standard play, but what other cards does Beastbinder interact with that have bugs? Figured better to report it than not.
