My take on Eldrazi Tron with an aggro focus. This is adapted from a Legacy Eldrazi 12 post I have had some success with.
I made a few changes due to playing in our meta.
Urza lands, Eldrazi Temple, Cavern of Souls & Expedition map are the key for mana base. 4 Wastes for Blood Moon but mostly for path & Field of Ruin. Blast Zone and Field of Ruin are searchable. Currently running 25 lands because of Blast Zone. I am pretty comfortable with this, it helps in games when you don't hit the Urza set I have yet to not get a Waste from things like Path to Exile.
Creatures
Reality Smasher is the primary killer.
Thought-knot Seer is great hand control and big body.
Matter Reshaper is a constant star in this deck, he often dies to hit an Urza land, which goes directly into play.
Endbringer is card advantage/large body and utility.
The Titans are just great and not all that hard to get into play.
Void Winnower is surprisingly good. He stops a fair amount of good cards and makes the swing for win easier.
Karn is for utility.
Ugin The Ineffable is great for cards and utility but is mostly in for his OP 2 reduction on colorless. Many cards now drop for 0,1 or 2. So nice! This card has won many games.
Ugin the Spirit Dragon, is a nice win-con as well as alternate board wipe.
All is dust is 2 of. I have added another to the board.
Mind stone is very good when you don't hit the Urza combo and it helps get to 6 which is key for Ugin to fuel the deck. They also replace mid to late game.
Strionic Resonator is just a fun card with some great usefulness. I am not currently running this and probably won't but it has been a nice twist.
Basilisk Collar could move to the side board but it generally helps me with fast aggro decks and burn. That few life I gain usually helps curve me out to the win.
Any comments are welcome.
