Experience counter

Experience counters are used to track a commander's growth in power over the course of the game. They are only used on cards designed for multiplayer formats.
==Description==
Unlike most other counters, experience counters are placed on players, rather than on permanents. Experience counters first appeared through a cycle of commander in Commander 2015. Each legendary creature in the cycle has a triggered ability that grants its controller an experience counter, and a second ability that benefits from experience counters.
Because experience counters are put on players, they stay on you even if a commander dies. Additionally, multiple cards in this cycle could accumulate counters in tandem.
===History===
Experience counters returned in Commander 2020, Commander Legends: Battle for Baldur's Gate, Phyrexia: All Will Be One, and Modern Horizons 3 Commander decks with <c>Kelsien, the Plague</c>; <c>Minthara, Merciless Soul</c>; <c>Otharri, Suns' Glory</c> and <c>Azlask, the Swelling Scourge</c> respectively.
==Ruling==
*All experience counters are identical, no matter how you got them. For example, <c>Ezuri, Claw of Progress</c>'s last ability will count experience counters that you got from the first ability, from another ability, from proliferating, and so on.
