Using

is an action you can perform that refers to using Option cards. The action can also be performed by effects.
== How to Use==
Using is an action you do in the following order:
#Choose an Option card from your hand that you wish to use and reveal it.
#* If its Use Cost would put the memory over 10 on the opponent's side you cannot choose that Option card.
#*If you do not have a Digimon or Tamer in the Breeding Area or Battle Area with the same colour you cannot choose that Option card.
#**Option cards with 2 colours require both colours.
#**White Options are not excluded from this condition.
#**Some Option cards have effects that allow the colour requirement to be ignored.
# Effects that specify "when you would use" are triggered and activated at this time.
#*In Japanese it will be "when using", some English cards used a literal translations instead of the Detailed Rulebook Standardisation.
#*These effects would have to be Interruptive Effects to trigger and activate at this time.
#Pay the newly reduced memory cost.
#The Option card is considered to have been "used". So, "when an Option is used" effects meet their condition, but they do not trigger at this time.
#Activate the Option card's effect.
#Trigger any "when an Option is used" effects and any effects triggered by the effect.
=== Important Notes===
*Activating the effect of an Option card is not considered "using an Option".
*Activating the effect of an Option card is not considered "using an Option".
An Option card is only considered "used" if the above process has been followed. You can still use an Option card even if the activated effect would not have a target.
