Omen counter

Omen counters are a type of counter introduced in Prophecy. They act as markers leading up to either an alternate-win condition or the transform mechanic to activate after a certain number of them build up or are removed. This represents the 'Omen' in their name as they lead up to an event happening.
==Description==
Omen counters first appeared on <c>Celestial Convergence</c> in Prophecy. It acts as a tracker for an alternate-win condition whereas the enchantment enters play with 7 Omen counters on it with 1 removed each Upkeep. When no more counters remain, then the player with the highest life wins the game or it ends in a draw of the players have equal life. 
The counters appeared once again in Innistrad: Crimson Vow on <c>Foreboding Statue</c> and <c>Soulcipher Board</c>. In both of these cases, they acted as a marker for the transform mechanic. For Foreboding Statue, it had an ability that added an omen counter to it when activated. It would then transform into <c>Forsaken Thresher</c> after having 3 or more of the counters on it. For Soulcipher Board, it enters play with 3 omen counters on it and one is removed for each card that enters the graveyard. It then transforms into <c>Cipherbound Spirit</c> when all the counters are removed.
