I think Firebat was the first to try this so it's not exactly an original idea. The plan is to corrupt your dunk tanks and medics then play them (just to stay alive) and get them back with y'shaarj later.

You keep the tour guides so you can double battlecry your y'shaarj and get all your copies of dunk tank and medics back and you send those face to finish your opponent. Each medic is 8 damage and 2 dunk tanks are 8, so the max (without generating anymore through lackeys) is 16 + 8 so 24 damage burst in one turn. if you have the rune dagger its 26 (plus 1 from weapon swing assuming it goes face). its not exactly otk but its quest shaman so you should be generating enough value to push some damage throughout the game.

If the burst is not enough, pen flinger might be a good addition to the deck. you can also consider diligent notetaker to get more copies of dunk tank. its actually a very strong card to copy but getting dunk tank corrupted then playing it after you have played a diligent notetaker is extremely slow, I don't know how realistic it is to expect that to happen often enough to be worth it. There's no other spells you need to copy in the deck (except generated ones from wandmaker + lackeys) so diligent notetaker would otherwise be a dead card most of the time.
