DESCRIPTION
Two main combos here.
First is Spine of Ish Sah, Trading Post and Possessed Portal. Play Spine, destroy a permanent. Use Post to sack Spine, returning it to your hand and drawing a card. Play the spine again. If you prefer, play two spines and use the possessed portal as your sacrifice engine. Neither player draws, you get to destroy all your opponent's stuff and when they have nothing in their hand or on the field, sack the portal to itself and proceed to kill them with staff of nin and treasure mages.
The other combo is the simplest one. Academy Ruins and Mindslaver lock. Play the Mindslaver, crack it, use ruins to put it on top of your library, lather, rinse, repeat until they concede.
Sideboard is mostly just for my local play group, feel free to modify as needed.
