The card take flight in the fairy packs doesn't work as listed. It says:
Start of turn-gain 1 hp.
play to gain 3 hp and draw a card
But if held it takes 5 mana at start of turn and discards a card from deck meaning if you ended the turn with 2 in hand you'd lose the 10 mana every turn losing by default.
Aside from that fun game but please update its def or change the info on the card.
