Ooo, a storm effe-
*reads card description*
...oh. So a massive 'rewind' effect?
Not to bash your idea, but I can already see an incredibly annoying move where the opponent has a lot of creatures set up, and then BAM, you rewind all of them while potentially denying him the chance of having some sort of offensive. Add onto the fact that
already has at least 4 other ways to control creatures (Unstable Gas, Eagle's Eye, Shockwave, and Thunderstorm), this would be one vastly annoying spell to use if you have multiples in your hands. Almost every False God could be rendered useless by this card alone (except Divine Glory or other decks that emphasize immortalized creatures).
Also, you should answer these questions in your notes:
-In 'what' order do creatures get returned to the player's/enemy's hand? From strongest attack to least attack (thus, they can play a dragonfly if that was rewound last) or from weakest to strongest (they can potentially play a dragon if that was rewound last)?
-Should the upgraded version simply just affect your enemy?
-How does this work against creatures with equal attack power? (Say, a Fallen Elf, Firefly Queen, Otyugh with 3|5, and a Horned Frog)
In your table, you should also correct the following:
-Remove (ftw) from the Elements part of your table
-Capitlize 'Spell', and simply remove the 'it has none
' from the Attack | HP part of the table. Replace it with a '-' (hyphen) or just leave it blank
-State your name in the 'Idea by' section of the lower table
-Try to find the link of the image if you can, even though it's probably obvious that the image is royalty free - if it's on the sxc.hu website, look it up there and post the link to the image in question
Oh, and my personal suggestion for improving the clarity of the card description, based on my Description Workshop (
http://elementscommunity.org/forum/index.php/topic,9851.0.html):
"Return all non-immortal creatures to their owner's hand according to attack order."
Where the highlighted part can be either one of those words depending on how you answer my question above. 
EDIT: Okay, realized it was based on attack ORDER, not attack STRENGTH.
