Eddie Brock / Venom, Lethal Protector (SPM) $28 Eddie Brock is one of my favorite cards from Marvels Spider-Man , and its what I expect from a good mythic thatll see Constructed play
Also, you need to save room for lands, creatures, and other non-Equipment cards
The Ulamogs The last of the three titans
This is a "suicide black" strategy: you need early ramp, low-cost reanimation spells, and creatures worth the life investment
To top things off, Timey-Wimey has an incredible mana base
Being able to maintain parity might be all you need and having a card that can keep you a bit safer early on and then go on to lock someone out of the game entirely is nice, it just requires fairly specific decks
