Can you rate my Magic the Gathering decks?

The mana ratio seems a little low, you should really have 24-25 lands in a deck (for the first deck that is), the 2nd deck seems to have a good number of lands. One thing you should be aware of is that while the first deck is tournament legal, the 2nd one is definitely not. Another issue I see with this deck is that you have a lot of singular cards. For a deck to be good you need to have 4 of each card not just 1.
