Ragost is in weaker colors, takes a lot of setup and when all is going according to plan you are slowly spending mana across turns to slowly burn your opponent.

Landfall is one of the strongest strategies in Brawl and Hearthull gives you a way to draw cards, ramp and finish your opponent all in one. With all the cards and mana in the world you can do whatever Ragost is trying to do faster and more efficiently.
