plains/swamp; [casual] right track?

Ok ill start with the land. 25 land in a deck allways feels excessive to me. Normally the decks im playing run on 20 or less mana. i just use creative ways to compensate for this. I will explain a lil more later.

I would most likely pull all three shimmering grotto. Why pay one mana for a mana of any color when your only playing 2 colors. an option here would be orzhov guild gate. It comes into play tapped but you dont have to pay one mana to effectively use it.

Haunted Fengraf produces only colorless mana and its ability is so so at best. if you get this land in a opening draw it would hurt you really badly. especially if its the only land you draw. So ide kick it to the curb like last weeks girlfriend.

Onto the creature business.
Ok so my philosphy for white is that its strong on getting rid of artifacts and enchantments, in addition to having powerful early attackers. I mention this because the pride guardian feels awkward to me. If your playing a creature heavy deck and plan to win by attacking. Why not cast a small white 1/1 with a random ability. I would most likely throw in a dutiful thrull or a tundra wolf for a second turn attack.

Now for the spells.
Disentomb seems kind of weak in this deck. how many large creatures will you be able to bring back to your hand late game? I feel that pulling this and adding another creature of some sort may be a better idea.

Mires toll is a bit off. Here is why your oppoent gets to choose 2 cards. So if you play it first or second turn he will most likely show 2 cards he doesint mind losing. As for late game your opponent should have a empty hand depending on their strategy. So if you can only play it on your turn then it might be waste of a draw. Or swap it for duress.

I like evil presence as a sideboard card. Load up 4 of them in a match against a non black deck and you will limit their available mana. As for main deck. Not to sure. Im sure some other smaller creatures would be more help with getting creatures out. Ive allways liked the blood pet.

Thats my input. So just by looking at the cards ide say more small creatures with abilities that have helpful abilities.

I took the liberty to look at the inventory you currently have posted and create my version of a Swamp/Plains deck.  This is what I came up with: http://deckbox.org/sets/400593

When I build my decks, I try to maintain a balance between high powered creatures and low cost spells as well as a proportion between my lands and everything else.  My land/everything else proportion is 40/60.  Forty percent lands, and sixty percent everything else. (That's 24 lands, and 36 everything else in a 60 card deck.)  Then I pick out my planeswalkers if I want to use any.  Because 36 divided by 2 is 18, I subtract the number of planeswalkers from 18.  The number I have left is the number of creatures I'm going to include.  I sort my creatures in the select colors or theme or whatever by power plus toughness from largest to smallest.  Then I select and include up to four versions of a certain card from each pile until I have a total of 18 creatures and planeswalkers. (BTW - I did not do this on the sample because it would take too long, but I did include the strongest creatures.)  Next, I pick out my artifacts if I want to use any; then I subtract the number of artifacts from 18.  The number I have left is the number of enchantments, instants, and sorceries I'm going to include.  I sort those cards in the select color or theme or whatever by mana cost from smallest to largest.  Then I select and include up to four versions of a certain card from each pile until I have a total of 18 artifacts, enchantments, instants, and sorceries.  (BTW - I did not do this on the sample because it would take too long, but I did include the cheapest spells.)  Finally, I select the lands that I want to use sticking within my chosen color boundaries.  I sort the lands based on what kind of mana they produce with cards that produce two different mana colors choosing a side (eg - if I have two cards that produce both white and black or either white or black, one would side with the plains and the other would side with the swamps).  Colorless cards side with the color that has the least lands on its side.  Then I go to the Stats page, scroll down to the bottom, and look at the land numbers listed at the bottom left.  After subtracting my already chosen land numbers from those, I fill in the final basic lands completing the deck.

It's a long, confusing process, but it works very well.  You're not likely to get mana shafted or creature shafted, and you can be guaranteed to have a fairly good balance of everything you need.
