1. Beast Soul Swap returns a monster to the hand, and from the hand special summons a beast type monster card. Really, since it's back to the hand and out to the hand again, it's useless as of far. If it's not restricted to beast-for-beast trade, then at least you can get out Rare Metal Dragon but no... this card makes a -1 card advantage and that's all so far. We need more beast cards for this card to be potentially useful. As of now, stay away from it.
(The only card that somewhat works with this is Behemoth the King of All Animals, as it has the potential to call a lvl 7 while only using one tribute, but that's at the cost of 3 cards to do this. Why not just use one of those "this monster counts as 2 tributes for ______ type" cards?)
2. Your Rescue Cat combo defies the rules. You already normal summoned Rescue Cat, so you can't call Behemoth the King of All Animals on the same turn, unless Rescue Cat is flip summoned or special summoned. There's only 2 Giant Rat to do the special summoning for Rescue Cat, (which is by far the best way to use Rescue Cat), but that's only 2 cards out of 60? The chance of drawing the rat is 1/30, which is very low... Most decks use 3 Giant Rat in a total of 40 cards, making it 3/40, and even then some people still whine about how that's too low of a chance to draw the searchers. In order to further improve the chance, people will "deck thin" to reduce the total number by either wasting cards away to the graveyard (such as Magical Merchant) or draw multiple cards every turn to speed things up (such as Des Lacooda, or Tsuku-Dekoichi drawlock)
3. Even if we assume that the combo works, Call of Ill Omen only places the trap to be on top of your deck, meaning, you have to wait another turn to actually get the card. This is again, another -1 card advantage. Even if you got Lone Wolf, it's not hard to destroy Lone Wolf, and it's not hard to knock out your LP via the Chu-ske that only got 1200 attack power yet can't be killed either. Even a Tomato can knock off your LP through Chu-ske, and that's saying a lot =/
Now, even a Toon deck, which is arguably one of the weakest deck in the game, rivalling the Harpies in terms of how pathetic it is (but probably one of the msot fun decks there are, especially for me since I like Pegasus the most ^_^). It got the combined weakness of both A Legendary Ocean deck with Burn Deck. It relies on stall cards and a continous magic card in order to survive. Destroy Toon World and the deck is basically gone. Comparing it to this deck, however...
a) Toonworld got Masked Sorcerer and Des Lacooda for a promising maximum of 3 cards drawn per turn out of 40 cards (but usually just 2), as opposed to this deck's maximum of 1
b) Toonworld got Toon Index, one of the best searcher there is (in magic form too,) with the ability to call absolutely all monster cards on top of Toonworld itself in the toon deck except Magician of Faith, Sangan and Des Lacooda, out of 40 cards. This deck got Rescue Cat and Giant Rat, which is only in monster form and is searching out of 60 cards, without the ability to search for almost anything.
c) Toon deck got plenty of magic/trap cards that are absolutely necessary in protecting the low level toons (most importantly, Toon Masked Sorcerer) but this deck got only 3 cards out of 60 to destroy spells/traps.
d) Toon deck's damage output is higher than this deck... this deck only uses beatsticks (and even then it does not have that many strong cards) to do damage, and with the lack of spell/trap destroyer, it will fall prey to almost any other decks. Toonworld can score crazy damage with Toon Gemini Elf (with hand destruction ability) and Toon Goblin Attack Force on top of the Wave Motion Cannon(s) if Toonworld isn't destroyed immediately. Toon world also may use Toon Cannon Soldier to do the finishing touch at late game.
So, how to improve your deck...
a) stay REAL close to 40 cards
b) every card should be able to stick close to a theme, and actually has a use at all times
c) for now, don't use any monster cards that got no effect
d) stay away from beasts for now, since it is a hard type to use well (it got no searcher but the Cats, and almost zero support.) For the sake of easiness so you can learn the game, go warrior or just plain old themeless cookie cutter deck.
e) Find ways for your deck to draw multiple cards, or can search out cards through special summoning, or a magic/trap search card
f) Always consider card advantage. How many cards do you have to invest in thsi one card in order to use its effect? A card such as monster reincarnation got bad card advantage, as it requires 2 cards (the one discard, and the Monster Reincarnation card itself) in order to use its effect. If bad card advantage is involved, then be sure to reconsider if the effect is *vital* to your deck or not. This deck doesn't require a specific monster vitally, so it probably doesn't need Monster Reincarnation. Now, a card like Cat of Ill Omen also got bad card advantage even though it got "no cost." It puts the trap on top of your deck. Now, you could have drawn a new card from the deck instead of the designated trap card, so it's still got a bad card advantage.
In rare cases, you need the bad card advantage in order to achieve something much greater. "Exchange of the Spirit" deck uses Exchange of the Spirit to deck the opponent out in a mere couple of turns. Sometimes however, Exchange of the Spirit (a trap card) maybe sent to the graveyard because it got destroyed by a Mystical Space Typhoon or got discarded by an attack from Spirit Reaper. Since this trap card is absolutely vital to the deck, the user may use A Feather from the Phoenix, which costs 3 cards (1 discard, 1 card on top of deck, and the Feather itself) to retrieve the Exchange of the Spirit. A Feather of the PHoenix probably got the worst card advantage in the game, but it's still vital to this deck because they're so dependent on Exchange of the Spirit being safe. They will sacrifice a lot to get it back. So, if you're using a card that cost you some resources (or, bad card advantage) be sure to consider if the effect is vital to your deck or not.
For now, I'll recommand you to probably copy a deck from someone for now *gasp* and learn how these "model deck" works. After you understand how powerful the concept of good card advantage through drawing multiple cards per turn, good methods of special summon and good synergy, then it'll be a lot easier to build your own deck.
Use a simple deck for now, a warrior deck, which is very easy to use. It's very friendly, and will do decently in most situations. It's not the best deck, but the point is that it's easy.

Again, it's not meant to be a very good deck, but just a good deck that's easy to use. This deck lacks draw engine, and personally i would have thrown in Dekoichi/Tsukuyomo for the drawlock...
You'll find exact copy of this deck in numerous amount of places, but just that the quantity of each card may vary.
