Looks good so far.
Yeh, it is supposed to be a risky card if you are looking for more rewards. But to reduce risk you can immediately turn the tadpoles to frogs cause frogs got better hp but by doing so you will end up with less tadpoles in the field since frogs don't have the tadpole's ability to produce another tadpole. So if you take the risk and somehow fill the field with tadpoles, then you can immediately convert them all into frogs.
It might seem imbalanced when you think that this single card can bring around 20+ frogs if they survive few turns but a single storm can kill all tadpoles and RoF can wipe out the entire frog army along with tadpoles. Also its a much expensive strategy than it seems at first since frogs are cheap 2 quanta creatures and you are paying 1 quanta and also waiting for one turn using this method.
I like this card, and the synergy it opens up. Anyway, I think it should be a 
card with 
cost. Just a feeling tho.
Great idea overall.
I think Tadpoles really spend their entire life under water until they grow into frogs. They are better considered belonging to water element.
Also tadpoles being water they can survive flood. Also Grow sounds like a
ability than a
ability.
