Anyone who owns between 100 and 1,000 rare cards should consider the platforms wide reach
Booster packs are meant to build the core of your deck, not the finer parts
Bloom Tender - $373.17 Set: Lorwyn Eclipsed Card #400 Japan Showcase Fracture Foil This is the same Bloom Tender from #9 on this list
I have seen this card used as a top end threat but without a fairly decent amount of ramp and good colour fixing I think it is a lot worse than Baneslayer or Wurmcoil in that sort of role
Also, to play into the fraction joke, every item, save Fraction Jackson, has only half of it appearing
Good card in zombie decks, and Id expect this price to go up in the long run (especially if the card gets broken), but not that high due to the restrictive mana cost
