In decks that can manage its triple green cost, Tribute to the World Tree plays like a less-absurd The Great Henge, which is one of the most powerful green card advantage engines
It taps for one colourless mana for each charge counter on it
That's nasty good in all of the places, like in tokens matter with Green dorks, aggro to refill your hand, or landfall making dorks like Insect tokens from Scute Swarm to draw a ton cards in decks with just Green or other colors like Simic Landfall or Selesnya Tokens
Theres not much point in putting The Locust God, Skullclamp, and Ashnods Altar in your Melek deck, for example, as you need to have all the pieces at once to get value out of any of them
As always, duplicate protection is not applied when you open 14-card packs in Limited events, such as Draft or Sealed
