So, since phasebot is acting strange, I figured I'd check some cases that remove stuff from the graveyard.
Phasebot DOESN'T copy itself if removed by: Purify (from deck, hand or GY), Cheryl, Wall of the Dead
Phasebot DOES copy itself if removed by: Soldier of Purity, Xi, Precautionary Measures, Grave Rob
So far not tested: Immortal Sufferer, Architect Orion
I can't test these myself as I don't have them. Feel free to do my work for me
Edit: Ooh, 100th post.
