Traveling the chromatic road, my goal is to one day have an EDH deck for each colour combination. I essentially only play EDH actively, but I do draft and cube on occasion.

I'm also a bit of a pennypincher, so my decks err on the budget side. I rarely buy anything valued above 5e, and usually keep my buys below 3e. Anything above that has been pulled from a pack or been part of a trade, or a random collection I've bought at some point or other.

Also, whilst I'm usually not much of a combo player, I do try to add an infinite combo or some degenerate end trigger as a wincon into each of my decks. This is mostly just so I have an off-chance to finish long, drawn out games spectacularly.

Additionally, I like to build each deck according to a small number of design restrictions, just so I can stay out of the staple pool as much as possible, and engineering decks stays interesting.

As a final note, I'm not a big fan of planeswalkers, so I only allow one 'walker for each of the decks.
