I tried to update the description a little better to hopefully clear up some confusions you had. L is the lifetime of the crop meaning how many rounds it sticks around before despawning. C is the candy you get per round meaning whenever you hit the bell. E is the energy cost. I explained the nbr aura flip and trick/treat in the description but just in case I'll explain here as well. There are 4 rounds per night and 3 of them are treat rounds in which the treat effect of a card applies but one round is randomly a trick round in which the trick effect applies. This can be seen just under the round counter where it tells you if its trick or treat. NBR is on the Frankencarrot and means it increases candy amount per neighboring crop which are the 8 surrounding squares of where you place it. On a trick round though you lose candy per neighboring crop instead of gaining (it can't go negative). AURA and FLIP work in similar ways. AURA increases the candy amounts of each neighboring crop which is more punishing on trick rounds but gives more bonus than the Frankencarrot. FLIP means all neighboring crops trigger their trick effects on treat round and their treat effects on trick rounds. Hope this clears everything up and can help anyone going forward.
