Ernham Djinn question

[BurningIce]

I was listening to my roommate teach his girlfriend how to play magic today, and he was explaining how Ernham Djinn works.  It made me think.  It says you can target a "non-Wall" on the card, but now with the wall rules changed to giving the creature "Defender", can you now apply the forestwalk ability to a non Wall Defender?

So long as the creature type is not Wall, yes you can target it with Djinn. This includes creatures with defender that have a non Wall creature type.

Many cards which previously specified the creature type 'Wall' were errataed when the ability defender was introduced.  Ernham Djinn, however, was not one of these cards.  Ernham Djinn's ability still says non-wall creature.  So, a wall without defender (Mistform Ultimus, for example) would not be a legal target, and a non-wall with defender would be a legal target.

As for other cards which used to specify 'Wall,' you basically need to check the Oracle for each one to see whether the current wording uses 'Wall' or 'Creature with defender.'  (Most use the latter)
