I will not deny that treetop dominion is now a powerful card, but to say it has no disadvantage compared to weathervane and more advantages is a mistake. Surprisingly, though borderlands has been out for a long time already, it still has not caught up to the metagame that was found in the borderlands beta. Borderlands has introduced several extremely powerful enchants and enchantment control is a must now. The fact that treetop dominion is a global enchant and hence always visible means that it is easier to use enchantment removal on it. There are plenty of useful enchantment control cards that still are seeing very little play because of the slowness of the spread of borderlands. But as these cards start to see more use, cards like treetop will be shown to have its own weaknesses.

I think the card is fine. Like Ilthid said global enchantments got some weaknesses (loxlorn globe etc.) that weather wane doesnt. But I do agree that it is better than Waether vane, but that is mostly because I dont think weather Vane is very good. Ix, Obervatory, Throne ond Lord is all better domain giving cards IMO.

As for its ability to create forests remember that Treetop doesnt create one forest each round, but it greens one field. Most games last between 15 and 25 turns. This will give you about 20 forests spread out all over the map, so you have to get a little lucky for them to turn up were you want them to.

Ok Let's try this:

"Enchant World

Gives {D,1,1} Domain if at least 5 forests are revealed to you, otherwise one random desert or grass space you can see is {A,Greened} at the end of the round."

MUCH BETTER. Enough said.
