Feather counter

Feather counters are a type of counter introduced in Invasion. They tend to grant bonuses or effects relating to birds.
==Description==
Feather counters first appeared on <c>Kangee, Aerie Keeper</c> in Invasion. It enters the battlefield with Feather counters on it if it was kicked. The counters grant +1/+1 to all birds on the battlefield. The counters appeared once again with the same effect in Judgment on <c>Soulcatchers' Aerie</c> which was an enchantment that gained a counter for every bird that is put into the player's graveyard. 
In Alara Reborn, Feather counters returned with a different effect for <c>Aven Mimeomancer</c>. It would put a Feather counter on a creature each turn which gave the creature aspects of itself making it have a 3/1 base power and toughness and flying. 
==Trivia==
* In Magic Online, the counter is colored green as its considered a positive effect and shares its icon with Velocity, Vortex, and Wind counters.
