Start crossing off ways to be defeated and enjoy the effects of purest invulnerability. Laugh as your opponent's tactics collapse against your impenetrable wall of wards and shields. With the Ultimate Shield, victory is undeniable.
The key to Ultimate Shield is the creation of the impenetrable wall. The first step is to create the ultimate defensive monsters, invulnerable to spell or attack. By combining Leonin Abunas, Mycosynth Lattice, Gaea's Herald, and Darksteel Forge, all permanents become indestructible, hexproof powerhouses. By gathering these three parts, you no longer need to fear destruction or countering spells, and your opponent's monsters are no threat.
Now that your field is safe from your opponent, the only thing left to protect is yourself. Combining Witchbane Orb and Platinum Angel means you cannot lose, and you cannot be targeted by spells to make you sacrifice. And because Platinum Angel is indestructible and hexproof, it is impossible to lose.
And once your wall is in place, all that's left is to watch your opponent's pale as your victory becomes all the more apparent.
