Don't know why there is so much hate on this sleep flower. It looks functional and fun to me. think of it as a level 1 creature(~5mana with 2 mana preinvested in the sleep spell) which can cast one(level 2 nature) sleep spell. added together, that should be 3 spellpoints, the same total mana cost, and not any less. And as for those who would prefer some sort of trap, this thing can trap just fine. The vine or seedling pod is the trap. If you have initiative, cast the flower in deployment, from a vine or defensive seedling pod then do the attack asap at beginning of round, or just quickcast it all.  If you cast the flower when you need the sleep effect, then there is no chance for it to die before the sleepening.

I would feel more at ease casting it before needing the sleep if the flower costed one less and the sleep costed one more though. The only big bad thing is that it has range 0 and can't move, which I'm fine with.  I am more worried about the Beastmaster getting a nature sleep spell from this card.  It doesnt compare well with the goblin slinger(lev2, 7 mana, soldier, 3 ranged attack which is actually ranged)
