Hahaha! Take that Dino Decks! This is even better than Crawling Dragon #2 because if someone twisters your field spell they still have to deal with a 1700 attacker instead of a 1600 attacker. Also trap removal (Harpies deck). Devastating.
I also realized however that this will likely go in a lot of people's decks. 1700 ATK is really good on its own (unlike the 1600 of Dino's) /and/ having these in your deck will protect you against Harpie Decks to a degree thanks to the fact that your Sonic Ducks will be affected by HHG as well.
