The sole reason being that besides Concealment, Vanishment etc. there are no counters for Awakend Plants (yeah there is Trickery)
I played with a lot of dream cards, but with this booster you do not need the other Awakend Plant creatures; Huorn & Old many Willow are enough, because
a) no one exspects these hazards
b) so no one brings any counters for them
c) huorn becomes the deadliest creature in the game since it is
2 @ 11 attacker chooses and a body of 5 keyed to one single wilderness
d) with Doors you have to face at least one every turn till you kill it
e) you're dead

Hazard long-event
All Awakened Plant attacks receive +2 prowess, +1 attack and attacker chooses defending characters; all Awakened Plant creature attacks with no body have 5 body.
At the end of each turn, each player may take one Awakened Plant hazard creature from his discard pile and shuffle it into his play deck. If Doors of Night is in play, the Awakened Plant hazard creature may be taken from discard pile to hand. Cannot be duplicated.
