Invitation counter

Invitation counters are a type of counter introduced in Innistrad: Crimson Vow. It acts as a counter for the transform mechanic of Double-faced cards.
==Description==
Invitation counters first appeared on <c>Wedding Announcement</c> in Innistrad: Crimson Vow. One of the counters is added to the enchantment at the beginning of the player's end step. After 3 or more counters build up on it, then it transforms into <c>Wedding Festivity</c>. The counters represent the invitations being sent out before the wedding starts. 
==Trivia==
*In Magic Online, the counter is colored green as it's considered a positive effect and shares its icon with Collection, Descent, Fetch, Oil, Mire, Slime and Soot counters.
