Eldrazi From The Black Lagoon (Standard)

"Eldrazi" + "Kailitos Traitor of Ghet" + "Liliana"+ "Devoid" counters/ removal spells = Hand Control, Graveyard Control, & Board control.

HAND CONTROL (Devoid spells/ creatures)
"Trangress the Mind" lets us see our opponents hand on turn 2 and exile their 3 mana or more costed threat.
"Mindmelter" is unblockable 2/2 that can easily be pumped to swing at opponents plainswalkers/ life total and has hand removal that exiles. "Liliana" (when she flips) forces the opponent and us to discard.
"Reality Smasher" has haste/trample and makes our opponent dicsard if they wish to target it.

GRAVEYARD CONTROL (Creatures/ Devoid Spells)
"Kailitos Traitor of Ghet" exiles your opponents creatures instead of sending them to grave.
(also He is a zombie token factory) "Horribly Awry" counters creatures of converted mana cost 4 or less and exiles them.
"Flaying tendrills" does -2/-2 to the board and exiles all creatures that die this turn.
"Liliana" has recursion abilities after flipping. (Her zombie she leaves behind when flipping also helps "Traitor of Ghet")

BOARD CONTROL
"Wasteland Strangler" puts an exiled card from your opponent into the grave to do -3/-3 to target creature for perfect early game removal. "Matter Reshaper" allows us to replace him when he dies or simply draw a card. "Hangar back" replaces himself with flying 1/1 tokens. "Ruination Guide" has ingest and boosts colorless creatures. "Drana" (flying, first strike) gives counters to our attackers when she does combat damage. "Eldrazi, Sky spawner" is a flyer that adds a token that can be sacrificed for mana or used as a chump blocker.

LANDS
"Ruins of Oran- Rief" allows us to put a counter on a colorless creature when it enters the field. (enters tapped, so best as a turn 1 play)
"Mirror Pool" allows us to copy Reality smasher and create a 5/5 token late game. (enters tapped, so best as your 6th land)
"Sunken hollow" allows for perfect fixing. (Comes in tapped unless you have two basics, so it is sometimes a great turn 1 play)
"Choked Estuary" allows for perfect fixing (Comes in tapped if you don't reveal a swamp or island which is easy early game, hard late game.) "Corrupted Crossroads" allows for untapped perfect fixing for most of our spells as they are mostly devoid but you lose 1 life.
We have more "Swamps" then "Islands" as our sideboard is mostly Black control and we have black creatures that require double black main board. Also basics help out "Sunken Hollow"
