Dream Halls

So I was wondering how can I use Conflux (The card, not the set) while looking through my friend's binder. Then I spotted a card I knew would work. Dream Halls. So I decided to build a deck around Conflux and Dream Halls

Creatures: 8
4x Birds of Paradise
4x Noble Hierarch

Non-creature Spells: 30
3x Call to Mind
4x Conflux
4x Cruel Ultimatum
4x Dream Halls
3x Enlightened Tutor
3x Force of Will
2x Grapeshot
4x Lotus Petal
1x Time Stretch
2x Time Warp

Lands: 22
4x Flooded Grove
6x Forest
2x Mystic Gate
4x Reflecting Pool
3x Vivid Creek
3x Vivid Grove

Basically, this deck uses Dream Halls to play Cruel Ultimatum. Since Cruel Ultimatum draws you cards,  more spells can be played, and Call to Mind can get back spells. If all else fails, use Grapeshot after playing ridiculous numbers of spells.
