I like it, but I have two questions:
- Why
Lava Dart when you can use
Shock instead?
- Aren't 20 lands too many?
Ok I have the answers myself, I'll post it here instead of deleting this because thus this can help others.
Using
Lava Dart triggers prowess twice.
And you need many mountains to pay for the costs of both
Lava Dart and
Fireblast too.
