A "this Digimon can't be attacked" effect prevents a Digimon from being chosen as the target upon an attack declaration, therefore an attack can be switched to a Digimon with such an effect by using an effect that switches the target after the attack declaration
While that is almost three times its original value, the Charizard only fetches the high value if it's determined to be in a perfect condition by a grading company
As of now, however, I wouldnt really advise trying to force an artificer typal deck to work
But its a legend you actually dont mind if they kill, since you can cast it again
In other words, this deck would never work in the current meta, but the Summoner of Illusions Quintet Magician-combo is cool none the less, hence this deck is considered a fun deck
Great, easy, smooth, experience
