What reason or rules prevents wizards to make it possible to also move the commander in the commandzone? I know its not a change of zones for the xommander but why not make an exception for phasing even tho its not a zone change. Should it really be possible to completely remove a commader from the game permenantly?

Are there any cards tvat prevent creatures to attack twice or only allow one battle phase? I play against a Xenagos Deck that one shots after resolving any additional battlephase.. I know about preventing combat damage for a turn but I was wondering if mtg has a mechanic for this
