First thing that I have to say, since they weakened the lily from 1/3 to 1/2, why not at least let it keep the point and make it 2/2?
As far as replacement goes, the new fusion pea card(can't remember what the name is atm) is pretty good. At 2/2 itself until you play a plant on it, the one bonus is it doesn't matter what lane whereas lily only buffed on heights. But you cant get the double lily buff or the shroom for two or pair o pears, velociradish two plant buff which was always nice. But this pea fusion as a 2/2 buff for 2, is a decent card and its more versatile than just a pea deck
