Kaiba thinks you're not worthy. Try to prove him wrong in theis 3rd installment of the card game series.
There are also a few computer-based loopholes that have been removed with this game. In Yugi's Destiny, Yugi never sets Spell cards, only Trap cards. Using your Trap Master's effect will always destroy one of his Trap cards. Conversely, if you set a Spell Card face down in position 1 (the leftmost of the five available card positions), Yugi's Trap Master card will always waste its Flip effect. Also, the only method Yugi has for taking cards from you is the Card Destruction spell card. If you have any super spell/trap cards, you can always set them on your first turn and Yugi cannot get to them from there. Try that with Kaiba, on the other hand, and he will introduce you to his Feather Duster, which wipes away all your set spell and trap cards. Rats.
In play still is the inefficient attack method used by the AI, almost always attacking with the weakest monster first. There are scenarios where you can be outmanned five monsters to one, and still win the duel by an AI opponent with ~500 life points left who decides to initiate the attack on your 2000 point DEF monster with its weakest attacking monster on the field. And Kaiba then says, 'How dare you!' - uhhh, okay.
Still, this game provides more instances where the AI just overwhelms you with superior cards out of the gate and never lets up. If you extend the duel and you own a Cyber Jar or two, you can strategically run Kaiba out of cards, winning the duel by deck attrition. This game provides more to think about in terms of strategy. Those games that are evenly matched as far as cards go can come down to the luck of the next card drawn (dare I say, the 'heart of the cards'...). Fortunately, playing on the AI's weaknesses will yield you many a victory that you might not ordinarily win. Oh well, Kaiba's problem not yours :-)
