Echo counter

Echo counters are a type of counter introduced in Mirage. They are used as a marker for an ability that allows them to essentially take the place of 1 damage that would have been dealt to a player.
==Description==
Echo counters first appeared on <c>Soul Echo</c> in Mirage. It is an enchantment that enters the battlefield with Echo counters equal to its additional mana cost. The enchantment makes it so the player does not lose the game for having 0 life and allows for an opponent to choose to remove a counter from it in place of dealing 1 damage to the player. The counters represent an echo of the player that absorbs some damage being dealt against them.
==Trivia==
In Magic Online, the counter is colored green as its considered a positive effect and it shares an icon with Awakening, Glyph, and Luck counters.
