Ignition Effect

Ignition Monster Effects require a manual activation by the card's controller during their Main Phase 1 or 2 (unless stated otherwise on the card). This type of effect used to be called a "Cost Effect" in the early days of Yu-Gi-Oh!, which was slightly confusing because not all of those monsters had a cost.

As of March 19th, 2011, these effects can no longer be activated in response to a monster's summon. Ex: You cannot activate the effect of "Lonefire Blossom" while you retain Priority when you summon it.

Examples of Monster Ignition Effects: "Cyber Gymnast", "XYZ-Dragon Cannon", "Bazoo the Soul-Eater", "Blackwing - Gale the Whirlwind", "3-Hump Lacooda", "Card Trooper", "Dark Simorgh", "Lonefire Blossom" and "XX-Saber Faultroll".
