No Eldrazi Colorless Aggro. I know, phyrexian mana has color, but who wants to pay mana when you can pay life!! Simple premise. Get out cheap fast unblockable creatures. Give them sharp pointy things.And then watch them become death!
Memnite may be the most underrated artifact creature. Zero for a 1/1. I know, i know, its still a 1/1. FOR ZERO. its a chump blocker 8 times out of 10, as is the Ornithoptor. However, as I stated, give them sharp pointy things...Sword of Truth or Justice!!! Gets around 2 of the most annoying colors in blue and white, makes an Ornithoptor into a 2/4, then when you hit you can make it a 4/6. Combined with the gentle love of a Steel Overseer or 4 and a nice homestead on Karn's Bastion....and suddenly you've got guys that can go toe to toe with anything....and don't even let me tell you why you have to put one onto a Gingerbrute!
Its actually surprising how well this deck seems to work. Give it a shot, tell me what you think, and as always, let me know what you would do better or different! Thanks and happy gaming!
update
So I took it to my local shop guru, he made a few suggestions, and now I feel its an even smoother, consistent deck. Added in Cranial Plating, Vault Skirge, and Signal Pest. Also trimmed the Field of Ruins. The extra land isn't really as needed, so more Ghost Quarters and Blast Zone. Also removed Karn's Bastion and the Wastes. Went with a couple Scrying Sheets and 4 Frostwalks instead because they add to my artifact count when I turn them on for the turn!!!
