Tactics cards with an attack count as an attack action

[rc_cuervo]

Good afternoon a question
When a player spends a card on which is an attack example:
magnetic crushing.
and uses this attack, spends one attack action or has his two attack actions apart.

[Negoldar]

Magnetic Crush allows Magneto to use the attack during his current activation. This will require the use of an action to use the attack. 

This is different from cards like Cruelty that grant an attack without using an action.
