It’s worrying. Maly Druid is already powerful. Can’t draw Maly? Now you will, using Melon. Can’t get Twig off? Never mind, dump Maly and Floop if it is killed or silenced.
That said, I wouldn’t be surprised if the expansion contains specific combo breaking cards (we have already seen one from Warlock, which turns a card in both hands into a demon). The designers are not dumb, they will realise that druid might be very OP if not checked.
