Somberwold Dryad
The somberwold Dryad is a powerful but affordable card in The Magic the Gathing card game. One of it's uniqe abilities is to become unblocakble as long as you control a forest. In other words, pretty much unblockable unless your opponent is playing a heavy blue control deck, in which case, your a bit screwed anyway. This might not seem like a lot considering her low strength and toughness scores, but getting her on the battlefield early and keeping her there can allow you to whittle away your opponents health one turn at a time, leading you to victory.
