Enough to blow up the field, but that's adding blue to the mix which once again defeats the whole true colorless concept. In which I Tinker Knowledge pool in turn 1-3. And steal said combo from you.
Some ideas to play with. A knowledge pool deck with shimmer myrs and 0 drop artifacts to steal whatever your opponents were going to do. A recurring mindslaver deck. Culling scales artifact deck with darksteel forge. Sands of time could be fun to mess with or teferi's puzzle box, timesifter, possessed portal, mimic vat and nevinyrral's disk with darksteel forge. Maybe put that culling scales card in there too with cards that just clear the field.
A person could make a "5 color" colorless scarecrow deck, but you won't be winning any tournaments with it, unless your running painter's servant and grindstone in which case you might as well be playing imperial painter and defeating the purpose of colorless. Lich's mirror is a interesting card. Build a deck where is soul purpose is to get a lich's mirror into play, and hoping the don't have cards to recycle their graveyards. Or some ganky combo with lifeline. You could try and play some kind of colorless control. Which would probably end up something like the old staxx or mud decks of legacy. Or a colorless version of moderns latern control with your ensnaring bridges and witchbane orbs for protection and elixars of immortality to survive your own slow mill. But people would probably hate you. Idk I'll do some research myself and see if I can find something.
I had the same problem when i was making this deck, ( http://tappedout.net/mtg-decks/every-turn-is-my-turn-1/ ) idk 3/4 years ago. There is absolutely nothing creative or original, its all affinty, tron, 12 post variants ohh I guess the new eldrazi variants. This deck is a blast to play with, and killing yourself instead of killing a table of multiplayer free for all is always entertaining.
I am curious to read your guys's on my list of Arcum, and to your opinions on where he stands on the tier list.
