another problem I just realise, when using the nymphs, I use their abilities basically once a turn, and for the deck to work well, you need one out atleast on the 5th/6th turn, and to end up with another one soonish, you also need a dragon too do damage, while the nymphs and the cells block and kill any enemy creatures, a big problem with strategy is that you're very succeptable to fast damage, tough creatures, weapons and permanent control.
