unionruler, that's actually incorrect. Zanz does have rules that he adheres to, and he always introduces new cards into the game strictly adhering to those rules. He changed the interaction between Rustler and SoR because of balance issues, but this is still considered to be an exception, not the rule. Momentum (which is a status, not an active or passive skill) is removable only by exception to the rule that only active skills are removable by Lobotomize. Nothing else.
