Yo chill dude.
Anyways using deflags or SoW both have their pros and cons. While SoW not only allows phase dragons to bypass pesky shields, they also give a neat attack boost, which deflags dont provide. However you are completely screwed against reflective shields, which while can be played around with by not using SoW, it results in dead cards in your deck.
On the other hand, there would be no problem against most shields with deflags, and it also has the added bonus of removing troublesome weapons such as pulverizer.
I havent actually tried out the card yet, but I suppose it will be a matter of preferance, and all's good as long as you are happy with what you are using
