I play a dragon deck and i wish i would draw this card more often.
I see the chance of drawing a common worth the cost/effect ratio. Most of the time its drawing a rare anyway since the rare-dragon cardset is so huge. Adding this little piece of text would not change that much most of the time. The main advantage, even if you just draw an uncommon or a common, is that you can free up an additional card on your hand. I often see myself not playing dragon egg because i need just to free up space to get something which gives recources, and hand manipulation is still very hard for dragon decks.
I would appreciate the change, although i don't see why the card really needs it. It just removes frustrating moments ^^.
