I dunno about this one. I have yet to see a Sai I actually like, and this one still doesn't do it for me.
The effect is a double-edged sword - your opponent's Jutsu cost more, but so do your own. Of course, Lightning traditionally has no problems generating Chakra, so you can pretty much cover your own bases there. Combine this with the anti-Chakra effects of Fire or Water decks, and you might be onto something.
Bottom line, it's a good card for slowing your opponent down, but playing it requires a great deal of planning on your part. You'll need to have a decent strategy to make up for your own handicap.
