Gagana dreams of meteors hitting Tarum [75% winrate?!]

Why use a 24-cost Dream combo, when you can use a 30-cost one?
With this deck, you play Gagana before Aurora's Dream. Then, you stick a Tarum close to your opponent's lands and use Meteors to destroy all their lands and the Tarum. The world fills with forests, replacing your opponent's lands.

The "75% winrate" in the title is true, and also a joke. (It's for just four games. I got the combo to work in my very first game with the deck in casual mode. Then, I played three games on ladder. In the first, my opponent gave up on turn 5 when they saw how much faeria I'd collected, on the second my opponent lost due to a disconnect, and on the third, I lost...which is pretty much what I'd expected to happen in the other three.)

Here's a screenshot of the moment before the combo goes off: https://i.imgur.com/fOyBWUo.jpg

(Credit for the combo idea goes to this deck here, https://www.faeria.com/the-hub/deck/3964-gaganas-dream. Instead of a mono-blue base, I went with a multi-color structure base, using Architect to buff Faeria Tree and Gabrian Cistern. I also added Ulani and another Curious Biomancer for targeted card draw to pick up the combo early.)
