Iruka Accurate analysis N-291

If an effect of a card is not valid, then when it is injured is its effect considered to be negated and therefor Iruka would provide a +1/+1?

If the above is correct and the question was posted in the stickies then please post a link since this rules question, since my tournament judge needs to see the clarification. thanks
