Honestly, I think theres fun to be had here with all of these decks, so pick the color trio you like best and just roll with it
Brimaz proliferates once at the end of your turn, like Atraxa, but needs a Phyrexian to have died under your control first
Although your opponent gets to put something out too, youre usually dropping an Emrakul or an Omniscience that ends the game before they can use their new toy
On top of that, this is slightly better than Farseek as it opens up for lands entering untapped - even if you would need to pay 2 health to do so, should you not wish to fetch the lone forest in the deck, as you would have to grab a shock land, of which where are three seperate hits
This led to the reworking of one final Masters release meant to be a sort of "Graveyard Masters" set and turned it into one heck of a juiced up release
