This appears to be a mildly interesting card but but the fact that it brings the land into play Tapped religates it from status as a potentially useful card down to mildly interesting.  Even if they print a whole cycle of them, they still dont result in more than mild interest or usefullness

Just a thought but why not put the Stuffy Combo into a Stax deck an alternate kill?  It's not harder that trying to use the Flame Vault Combo in the deck.  Depending on the build of course, Stax can support the white cost of the enchantment.  Plus Stuffy gives you a nice defense against Goblins.  "Hello Mr. Piledriver!  Would you be interested in doing a bunch of damage to your controller?  Really you would, then let me introduce you to my friend Stuffy Doll.  Hold still now while I weld him in." 

Just an insane thought from a insane person.

Ok Im sitting here reading through 3 pages of the discussion on the Children & all three pages say the same thing "this is a good card for Deck X to use as a weapon against Tendrils"  Ok thats fine & all but how about using the dumb thing offensively instead of defensively.  Imagine with me for a moment a Tendrils deck that uses the Children in it.  The interaction with both Necropotence & Yawgmoth's Bargain is just SICK!!!  "I'll Bargain/Necro for 19.  Play a Children.  Sac it.  Gain 19 life.  Bargain/Necro for 19 more.  Play another Children.  Sac it.  Gain 38 LIFE. Win"  Come on people.  That suddenly gives me the ability to draw WAY more than my entire deck.  These little guys can draw way more cards than Illusions ever thought of letting you draw. 

Just my thoughts on an interesting new card.
