This kind of just begs to put into an all high cost creature deck.
Basically, just copies of this card and a whole bunch of water dragons and / or nymph queens.
Not sure if that will be OP or not.
seems pretty balenced to me, in order to do that you lose all versatility, sure an ice bolt works but will it be worth putting in
It all comes down to the details... particularly the flown interactions...
Right now, 4
+ 2
and 3 cards yields this flown + 2 Dragons.
If the opponent doesn't frack it they will be facing a new dragon each turn until all 6 are in play.
Versatility?... You could have 6 dragons out by about turn 4. Who cares.
Ex: using time mark,
Turn1 Water towers
Turn2 This + animate + SoR -> 2 dragons
Turn3 activate then SoR then double activate -> 5 dragons
Turn4 active -> 6 dragons.
Barring any shields or heavy CC, that's a 4 turn win.
