This theme works on three levels: Payoffs (i.e., Judge Magister Gabranth, Al Bhed Salvagers) Sacrifice outlets (i.e., Phantom Train, Namazu Trader, Ahriman) Fodder (Hecteyes, job select equipment, Rufus Shinras poor disposable dog) A good WB deck has a healthy mix of all three, plus lots of strong removal spells like White Auracite and Sephiroth's Intervention
Hexproof creatures are still vulnerable to board wipes, but given that Snakeskin Veil can be played as an instant , you can use it to shut down a targeted spell first, and hope that your opponent doesn't have the mana or cards in hand to follow it up with anything else
Roo Littlest Pirate is a real menace for this, as the strength debuff lasts until your next turn
Your deck can only comprise cards of two different ink colours (Amber, Amethyst, Emerald, Steel, Ruby, Sapphire)
If a permanent with a shield counter is dealt unpreventable damage, that damage will be dealt and a shield counter will still be removed
