Gonti, Lord of Luxury is a beautiful card. Just by their own right, the ability to take anything you want from the opponent, and they'll never get to know what you took, is a glorious thing in itself, but the fact that Gonti can die or go back to your hand and you still can use whatever you exiled, is just amazing. Panharmonicon allows you to do this twice every time Gonti enters the battlefield. Now who would possibly ask for more?

Gonti.

Obviously.

So we get ourselves a Decoction Module and do this roughly once every two turns, your opponent didn't realize he was a making a deck for us to play, did he? What a silly person. Now we probably won or lost by now, but say the guy doesn't realize it yet. We drop down a Wispweaver Angel and now she lets Gonti to do their thing yet again. Well, we also have Panharmonicon out, meaning she can do it to two creatures at the same time; Gonti, Lord of Luxury and, say, Weaponcraft Enthusiast . Now we have the ability to play their Ulamog that they were banking on, and we also have about 4 Servos for whatever reason we wanted them. Thanks Wispweaver!

What? Oh we have two Wispweaver Angel s and a Panharmonicon? Not only do we get to infinitely bounce them over and over and over, but we can bounce Gonti... over and over and over! Gonti decided to steal ALL of the other player's cards! They can't even play anymore! We have their whole deck! What a silly person!

Now, Gonti takes a little while to get themselves up to speed and they like to take things pretty slow, so we have to work with them and make sure we can survive that early bad stuff like that pesky Pia Nalaar or that Smuggler's Copter, so we're employing the help of planeswalkers like Liliana, the Last Hope and Ob Nixilis Reignited to clear out the area and get Gonti back up on their feet if they tripped and fell into the graveyard or something. The graveyard is not very luxurious! For that copter, we even brought Sorin around so he can Anguished Unmaking that vehicle. If that's not enough then we might rely on a Blessed Alliance of some others to help out Gonti, so that Gonti can make a blessed alliance with the opponent's deck.

Now if none of that is working out, we have some alternatives available on the side. If the opponent is just running around way too fast with their RW aggro standard boring racer deck, then we can get some help from the Authority of the Consuls to slow their roll and survive a bit longer. Is the opponent running a lot of instants and sorceries and just being a nuisance? Well Gonti has the direct line to Kambal, Consul of Allocation, and that guy knows exactly what to do, though we'll probably owe him a few favors after (On top of the favors we already owe him). But maybe they're just bringing out all sorts of pesky little critters and there isn't much we can do if they're doing that, besides of course just Fumigateing the whole darn place. But maybe they decided they wanted a Liliana, the Last Hope of their own. Maybe they're getting help from Gideon, Ally of Zendikar, or even Nahiri, the Harbinger, Besides being sad that we can't play these cards ourselves, at least we can get them out of the way with a Ruinous Path or two or three.

But now that we are all set and the way is clear for Gonti to take all of the opponents deck and use freely whenever Gonti wishes, we should be good to go!
