Here's a deck idea Based around the Masticore (4/4 regen, creature kill for 4 mana)and the Cursed Scroll (1 mana caster does three damage if opponent picks the card in your hand that you say the name of)along with some other cards I really enjoy using to pummel my friends when we play.

The idea of using the masticore and the cursed scroll together is to
        1. Make it easier to get just one card in your hand so you can use the cursed scrolls more effeciently.
        2. Keep just one card in your hand.
Now I don't like to just sit there - not playing any cards - just so I can keep the masticore in play and the cursed scroll doing it's job, so I use Temporal Apeture (artifact- 2 caster, 5 mana to pull another card out of your library and put it into play.

I guess just these cards, with some Vaultic Keys and Thran Dynamos would be enough to crush about 20 life out of anyone and keep them from having any creatures, but where's the fun in that??

I like to use another great card combination:  Covetus Dragon (6/5 Flying for 5 mana as long as you've got an artifact), Fire Diamonds (2 caster...  Faster mana production and great with this next card), WildFire (4 damage to all creatures - not enough to kill covetous (masticore regenerates) - destroys almost everyone's lands, but you've got fire diamonds and thran dynamos!

Anyway...  Here's the whole deck:

Creatures:
        4 Covetous Dragons
        4 Avalanche Riders
       
Enchantments/Instants/Sorceries:
        4 WildFires
        2 Shattering Pulses
        4 Pillage
       
Artifacts:
        4 Fire Diamonds
        4 Thran Dynamos
        4 Cursed Scrolls
        2 Masticores
        1 Grim Monolith (more if you're playing with friends and want to be a dick)
        1 Vaultic Key (same as above)
        1 Sol Ring (again, more if you'd like to be cussed at quite a bit)
        2 Worn Powerstones
        2 Temporal Adeptures

Lands:
        4 City of Traitors
        4 Ancient Tombs
        13 Mountains

Tips:   Just do whatever...  You'll win!
