It's freaking Strip Mine. I don't think I need to explain it.
Lake of the Dead
This card can really give you a much-needed mana boost at the right moment. It's a 4-mana boost and that could easily win you a game.
Another mana boost-style land. Yeah, it requires land sacrifice, but it a deck that has a lot of "untap target land" effects can change the amount of mana from one land from 2 to 6. Again, that's enough mana to win you a game.
A land that makes tokens? Awesome. A land that makes useful tokens? Awesomer.
It's kind of like a colourless Alchemist's Refuge and that makes it pretty cool. Most decks can use flash creatures and this card makes it possible.
Oran-Rief, the Vastwood
Your green token deck will love this card. If I have to explain why, you probably shouldn't be playing a green token deck.
