Forum:Karakuris with Scrap Iron Scarecrow

Hi I'm running Karakuris and I was considering putting in Scrap Iron Scarecrow, but I want to be clear on something. Karakuris change into defense when selected as an attack target, as you should know. However, if an attack is negated by Scrap Iron Scarecrow or similar card, would the effect still activate? Obviously the attack doesn't go through but does it still count as having been selected as a target?
