Forum:Tips on my Beast Deck

Can you guys give me ideas on how to improve this deck? (Please try to keep it at exactly 40 cards)

MONSTERS: 1: Ojama Green 1: Ojama Black 1: Ojama Yellow 1: Andro Sphinx 1: Sphinx Teleia 1: Theinen The Great Sphinx 2: Hane- Hane 1: Mystic Horseman 1: Maji-Gire Panda 1: Rescue Cat 1: The All-Seeing White Tiger 1: Bubonic Vermin 1: D.D Crazy Beast 1:Nimble Momonga 1: Two Thousand Needles 1: 3-Hump Lacooda 1: Beast Koala 1: The Trojan Horse (TOTAL: 20)

FUSION DECK: 1: Ojama King

SPELL CARDS: 1: Ojamagic 1: Swords of Revealing Light 1: Mystical Space Typhoon 1: Ring of Magnetism 1: Double Attack (I need a substitute for this card) 1: Polymerization 1: Poison of the Old Man 1:Fusion Sage 1:Reload 1:Dark World Lightning (TOTAL: 10)

TRAP CARDS: 1: Solar Ray 1: Curse of Royal 1: Magic Jammer 1: Backup soldier 1: Ray of Hope 1:Covering Fire 1:Gorgon's Eye 1:Hidden Book of Spells 1:Pyramid of Light 1:Trap Hole (TOTAL: 10)

Please try to find a good substitute for Double Attack because i have almost no use for it and can't decide on what to put in for it.
