The deck seems a little strange. You've got a crucible in your deck, but on the other hand, there are only penny cards in the land base. If you want to upgrade the deck, i would suggest to start there.
Btw,
Temple of the false God is a noob trap. Yes, 2 mana out of one land may sound nice,
but you need to get 4 other lands out first. Until you manage to do this, its a
dead card, in particular if you got the temple on the opening hand.
Then i would think about
Tempt with Discovery. I dont know about the mana base of other players in your group, but the chances are high, that they will
profit more out of this than you. If you want to keep it, i suggest adding Ghost Quater or another land that allows you to remove other lands (I prefere
Tectonic Edge), in case someone takes the chance and gets some nasty stuff.
