M14 Core set introduces Rule Changes:
- Legend Rule now looks at each player individually. You can now have two Geists of Saint trafts on opposite ends of the board.
- Same applies to Planeswalker uniqueness rules. (You can no longer kill off an opponent’s JTMS with a Jace Beleren)
- Sideboard is now UP TO 15 cards. (Not 15 or 0)
- Indestructable is also now a keyword. (it can be removed by things such as humility)
- Unblockable is now NOT a keyword
