I'm looking for Card Battle games for Android

There are plenty in Google Play, but they require internet connection to play.
Is there any Card Battle game that works offline?
Single player campaign or battles against AI.

Recently Card Wars and Card City Nights were released. That's the kind of game I'm looking for.
Is there something more Yu-Gi-Oh style?

This Spellstorm game seems great, you can summon the monsters from the cards, fight and all,
but it too requires internet connection to play.
