Editing Ignition Effect

'''Ignition Effects''' (Japanese: 起動効果 ''Kidō Kōka'', "Startup effect") are [[Spell Speed 1]] monster effects that require a manual [[activate|activation]] by the card's [[controller]] during their [[Main Phase]]. This type of [[effect]] used to be called a '''Cost Effect''' in the early days of ''[[Yu-Gi-Oh!]]'',{{citation needed}} which was slightly confusing because not all of those [[Monster Card|monsters]] had a [[cost]].

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.

==Priority==
Under previous rules, it was possible to activate an Ignition Effect in [[response]] to the monster's own Summon. This was removed from the ''[[OCG]]'' on March 19, 2011, and from the ''[[TCG]]'' on April 25, 2012. Ignition Effects can now only be activated during an open [[game state]].

When the [[turn player]] Summoned a monster with an Ignition Effect, because they had [[priority]] to activate an effect, they could activate the Summoned monster's Ignition Effect before the opponent could activate a [[fast effect]].

For example, the turn player could [[Summon]] "[[Lonefire Blossom]]" and activate its effect before their opponent could activate "[[Eatgaboon]]".
