Ignition Monster Effects (Japanese: 起動効果 Kidō Kōka, "Startup effect") are Spell Speed 1 effects that require a manual activation by the card's controller during their own Main Phase 1 or 2. 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.
Examples of monsters with 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 most Xyz Monsters.
Post-Problem-Solving Card Text, these type of effects will generally be indicated by "Once per turn:", "You can" or "During your Main Phase:", followed by the cost which will end with a semi-colon(;), and lastly, the actual effect which you activated.
Previously, the turn player had priority to activate Ignition Effects before an opponent could activate a fast effect. This was removed from the OCG on March 19, 2011, and from the TCG on April 25, 2012.
