Now that I found out what Soul Exchange does (thanx to this website and everyone on it) I've thought of a few combos for it,  most of them while dueling.  Incase you dont know what it does here's an easy explanation : If your doing a move that requires you to tribute(sacrafice) one your monsters you can use Soul Excange and you can use one of your opponent's monsters for the tribute.  So here they are:

1) If your opponent has 2 monsters out (specially 2 strong monsters) use Soul Ex. with Tribute to the Doomed and BAM!! There goes 2 of your opponent's monsters, probably leaving him open for Direct Attacks
2) Use Soul Ex. with Catapult Turtle to cause Direct Damage equal to half of the atk points of the monster tributed.
3) Same as #2 except replace Catapult Tur. with Cannon Soldier to cause 500 points of direct damage.
4) Same as #1 but with Share the Pain
5)Just so that this will be short you can use Sou Ex. with anything that requires you to tribute one of your monsters.

There u go I'm sure it helped out clarifly this card and shown you its true power. Laterz for now..........
