There have been many of these "you can have any/a specific number of these in your deck cards". Shadowborn Apostle, Dragon's Approach, Templar Knight and Nazgul are some of the examples. However, after watching of one SaffronOlive's recent video, card:Slime Agains Humanity peaked my interest. Most of these type of cards are meant to be on the battlefield to provide some additional benefit, with the exception of Dragon's Approach which needs to have some in the graveyard. However, card:Slime Agains Humnaity takes on a different approach. Is it good to have many in the graveyard? Yes, but it also has the unique distinction of not being worried about graveyard hate. Even effects such as Surgical Extraction aren't necessarily the end of the world because they benefit from being in exile and I want to try a card that, at least according to MTGTop8, has barely seen play in the last 10 years, Research / Development.
While I always have some janky deck ideia, this one is peaking my interest due to its uniqueness in playstyle. It's not necessarily a como deck, such as Neobrand or Storm, where you instantly win by just having the combo. Instead, you need to sculpt your opening hand to have a favorable match. Besides this, I'm also using this opportuniy to play another card I've been wanting to use for a long time, Collected Conjuring.
What's the game plan? Show
As the name of the deck suggests, the idea is to manipulate the opening hand with cards such as card:Serum Power to exile as many Slime Against Humanity as possible to make the first Ooze strong. After the mulligans, Devourer of Destiny can help a bit more by exiling more Slime Against Humanity and possibly find something worth keeping at the top.
I hope this deck is what brings me back to deckbuild again and hopefully I continue to update it and also some of my older decks.
Of course, this is far from a polished list and there's a lot that can be worked on, such as interaction, card draw/advantage, protection, etc.
