The Tilt-inator (Modern) [Revisione 17]

This deck wants to do some shenanigans with Solemnity and any other card that utilizes counters. As for the win-condition, we play Altar of Dementia for the combo-win and we could theoretically also just beat the opponent down with Phyrexian Soulgorger.

So at first we play four copies of Altar of Dementia, as it combos with Solemnity, Kitchen Finks and / or Safehold Elite. With that, we can mill the opponent out in one turn, once we assembled the combo.
The combo works like this:
We sacrifice one of our persist-creatures for Altar of Dementia, mill the opponent for X. Because of the persist ability of our creature, it will come back, but as no -1/-1 counters are put on them because of Solemnity, we can sacrifice them again with Altar of Dementia and get them back again, which wouldn't be possible without Solemnity, as the persist-ability only gets them back, when no -1/-1 counters are on the creature. This loop we can repeat infinetily.

Of course we play four copies of Solemnity. I don't think tutors are required, as we have a lot of Howling Mine to dig for Solemnity early.

For some control, we play four cheap counterspells with Mana Tithe. For the best removal in the format, we play Path to Exile. As we don't have any good card draw nor scrying in white, and my all-time favourite for digging in non-blue colors, Mazemind Tome, is disabled by Solemnity, I had to include something group-huggy with Font of Mythos. It doesn't generate card advantage but digs for our pieces and technically our cards are worth more, as we are able to play out an infinite-combo.

For the synergies with Solemnity, we play eight persisters, with Safehold Elite and Kitchen Finks, both enabling the combo with Altar of Dementia. They are also pretty good by themselves, providing unlimited blocks, if we have Solemnity on board. For the addtional win-condition and otherwise just good blocker, we play Phyrexian Soulgorger. It's extremely efficient manawise and it's drawback, which makes it unplayable, normally, is just disabled by Solemnity. So if we have Solemnity, it's an vanilla 8/8 for three mana.
As for my main reason to build this deck, we have Phyrexian Unlife. It buys us an unlimited amount of time to find our combo-pieces, as we don't die from damage, but neither from the infect counters, that Phyrexian Unlife is trying to put on us when we receive damage, as we can't get counters with Solemnity on board.

For the most budget mana-base in human history, we play 24 plains.

I tried to make this deck as budget as possible, but it still ended up at about 50€ on cardmarket. But this is still pretty budget.
