It's not easy to summon 7 creatures into field when you hold this in hand.
I'm afraid this card will be another new card design for FG deck and collecting only...
If the ability will also work in the middle row with Flooding, this card will be more useful for players.
May also change it will DRY without water(Flooding). Or no reduce to fire(poison still hurt but no stack). 
Or you could fill the field up with it using Mitosis or Fractal.
