Wizards have been moving away from symmetric effects, but I think that's more important when something affects, say, white creatures, and mostly that just benefits you, but your opponent happens to have one or two white creatures and they randomly get better and both players find it easy to forget.
Since almost all decks play with creatures, I think the downside here is worth it, but still exploitable if you have more smaller creatures.
I'm not quite sure of the cost. White gets one-sided +1/+1 for . It must be less good on an artifact, but how much worse?
Thran Weaponry said it was -and-, which usually works out about equivalent to . Well, with the minor benefit that you can choose to turn it off and on. So for this simpler version is probably fairly close.
Ah! I looked for an existing card, but missed Thran Weaponry somehow. It does seem unnecessarily complicated; the three word version looks a lot more exciting than the 40-word version.
(I suppose you might get some use out of the optionalness by attacking and waiting to turn it on until you see how the opponent blocks. But that seems to add a lot of complexity and not much fun.)

4+4+2 that is. And the echo didn't work with that extra
very well... which is an odd choice. Why didn't they just cost this 
?
