How good is my synchro deck?please rate it and give any suggestions?

Pretty good deck. Well rounded. I give it a solid 8.5/10. The only thing that kind of bothers me, is that you have things like Waboku and Threatening Roar, where a Scrap-Iron Scarecrow is soooooo much better. Having three on the field will be able to negate three attacks from your opponents monsters. Another thing I would like to add, is that you should think about putting in a Colossal Fighter because of all the warriors you have. Someting I like to do is to tune like a Gaia, Force of Earth, with a lowly lvl two monster, so that Colossal Fighter can get that extra 100 points of advantage from the Gaia. You can also do it with a Junk warrior too. Also, a good combo with Spell Striker, is a Heart of Clear Water, which makes it indestructible from attacks and effects that specifically target it. The only thing that is able to stop it is Lightning Vortex.
