Please fix Zada, Hedron Grinder

So I was really excited when I opened Zada, Hedron Grinder until I discovered that his ability doesn't work on himself. So when you cast a spell on him, he will not gain +6/+6, only your other creatures will (if you have any). His ability clearly reads "all your creatures" with no use of the word "other", so it's very apparent that it's not working correctly.

On a related note, I discovered that Turn Against cannot be cast on your own creatures despite no mention of being restricted to your opponents creatures (unlike Act of Treason). In regular Magic, such cards can be cast on your creatures to give them Haste even though you already control them. I was hoping to be able to use this card in my Zada deck as a cheap way to give him Haste and +6/+6, but Zada isn't considered a valid target.

Please fix these issues so can I enjoy my Zada deck. Thanks.
