good trap combo-

Eye of Truth
Bad Reaction to Simochi


these two traps will deal 1 thousand damage per turn at your opponent's 
standby phase if they have a magic card in their hand.

Another combo-

Soul Release
Graverobber's Retribution

use sould release to remove as many monsters as you can in you opponent's 
graveyard, they will lose life x100 by the amount of monsters removed per 
standby phase,

(you can use more soul releases if you want to inflict more damage)

Another combo

Card Shuffle
Convulsion of Nature

use convulsion of nature to flip decks upside down, then you can shuffle 
when you don't want your opponent to get something good, you can also 
shuffle yours to get something good.
