Great card.But I think they multiply too fast.Possible variant: tadpole becomes delayed for 1 turn right after it spawns another tadpole.
1) place a pair of tadpoles2) stall, stall3) ARRATATATATATATATAT 23 5 att creatures = enough to bypass diamond shield. tadpole OTK.
I really like this idea, about time their is and synergy . Can't wait!
