Ignition Effect
Ignition Monster Effects are Spell Speed 1 effects that require a manual activation by the card's controller during the Main Phase 1 or 2 of the controller's turn (except "Red-Eyes Wyvern", "Daigusto Eguls", "Speed Warrior" and "General Gantala of the Ice Barrier"). 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, for the OCG only, these effects can no longer be activated in response to a monster's Summon; e.g. In the OCG, 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", "XX-Saber Faultroll" and almost all Xyz monsters.
