I have a friend who uses this card and two friends who play blue. We play multiplayer all the time usually with 4-6 people. My friend has done very well with just one of these cards in play. He wants to get 3 more to add to his arsenal. I'm going to get 4 for my green deck.

First of all, this card is obviously limited by the opponent that you are playing. However, if you know you are playing blue or a blue combo deck then this card has some use. It could be used inside a Elf or Druid deck maybe. On the other hand, I do not think that this card has a place inside a green aggro deck. An aggro player usually is focused on mana boosting and pushing large creatures. They are generally not very interested in life gain when going for the quick kill. One last things to mention is that blue decks are usually very well equipped to destroy enchantments so I can't say how long this card would stay on the field.

End the end, this card is half decent for its limited uses, but other then that, don't bother.
