Rakdos Christmas Party (Modern) [Révision 29]

This deck wants to "gift" the opponent with permanents with heavy downsides, such as not being able to win, just losing the game, discarding cards or generating tokens for the opponent.
All that is provided by Akroan Horse, Abyssal Persecutor, Rotting Regisaur and Demonic Pact.

As we don't want to kill those cards, because their downsides are just too good for us, but we also don't want to just be beaten down by those high power creatures, we have Ensnaring Bridge, which we also could just gift to our opponent, because it still works the same and may be better on his board if he has zero cards in hand because of Rotting Regisaur.
For card draw or protential burn we have Browbeat. Early removal is provided by Lightning Bolt.

Rotting Regisaur is a perfect fit, as it synergyses with Ensnaring Bridge. Akroan Horse gifts itself to the opponent which is pretty good and it provides a win condition because it will pump out many tokens for us after some time. Abyssal Persecutor is not a win condition, but it buys us unlimited time to kill the opponent, if the opponent can't deal with it. Demonic Pact is our main win condition, as we can use the first three modes and then gift it to the opponent, him losing the game when we pass the turn.

To gift our stuff we have Harmless Offering and Bazaar Trader, with Bazaar Trader providing one gift a turn.

As most of our presents for the opponent are quite expensive, and we still have to summon them before getting rid of them, we packed 25 Lands.

It's semi-budget, with even a playset of Ensnaring Bridge in there, "only" costing 110€ and I don't think there's a way of removing that card from the deck, as board wipes and removal are not going to be any good, because we want to keep the opponents creatures on board.
