The Big Card

The Big Card is a tall spirit who has the power to greatly increase the size of the target. I personally think the card was just a filler that Sakura could capture casually in her spare time. Sakura just walked up to it and captured it. It however was useful about twenty minutes later when she faced off against all the Create Card's spooks and kooky looking critters.

When summoned by Sakura, it has the ability to either enchant the castor or the target the caster specifies to grow to the size that the caster wishes.
