Yes, that idea is awesome. My team would consist of Baraka and Scorpion. For their double team fatality, Baraka would impale the enemy with his blades, and mount him into the air. While doing so, Scorpion would roast him/her with his fire breath. Once crispy, they douse the enemy in BBQ sauce and eat the roasted corpse.

The Dream Team for me would have Sub-Zero and Scorpion on it.

Sub-Zero's and Scorpion's Fatality could have the use of both of the character's projectiles.

Scorpion throws his spear into the opponent's head and the opponent would fall to his or her knees. Sub-Zero would grab the rope Scorpion is holding and ice would shoot through the rope and freeze the opponent's head. Sub-Zero and Scorpion would then kick the opponent's head together and the head would explode into ice shards.

These are pretty cool keep them coming. Here's mine.
Smoke and Sub-Zero
Sub-Zero freezes the opponent solid. Smoke then rushes at the guy with twin plasma sabres. He impales the opponent with both sabres through the stomach in a cris cross pattern. Sub-Zero then jumps off of Smoke's shoulders and round house kicks the guy's head off. Smoke then takes out his sabers and cuts the guy into twenty pieces before the body thaws and explodes in a cloud of blood.
Or Sub-Zero freezes the guy then Smoke runs to the guy with his sabers, shoots the guy twenty feet into the air,Sub-Zero jumps up after him and ax kicks back down to the ground.As he comes down Smoke slices him into three pieces before he hits the ground with his sabers. the body falls into three pieces and shatters into shards of flesh and blood on the ground.

I really wish they would have added the tag feature as they did in Mk:Te, i thought that would be so fun. But if they did add the tag, they should make it so that u have to be in an arena with no death traps and stuff, because it would be weird, ur partner gets kill and then u pop in. Anyways, my team would be Sindel and Ermac
