EDH isn't a game meant for control to me personally. It's a game meant for silly synergies and impractical moments of awesome, again, allowing people to have cards breathe and interact. EDH I like because the cards breathing are more often than not underpowered or amusing. I have a rainbow machine-ish artifact deck whose sole purpose is to get
Filigree Angel out and gain a lot of life, then play
Platinum Emperion and
Darksteel Forge and feeling machiney and fortressy until the easily disruptable steel wall inevitably gets easily disrupted. The rest of the deck is mostly a lot of internal synergies that I adore to explore during the game (I simply seed the deck with all sorts of obviously combotastic artifacts - luckily without getting an infinite combo as of yet

). The deck simply lives and thrives and fails on synergy. I have two other EDH decks - an angel-dragon-glorious equipment WR deck mostly thrown together because I had too many of the cards not to do it; and a black sacrifice-graveyard-synergistic thing (similar to the pointlessness of the artifacts, but with less reliance on abilities of permanents) built around
Endrek Sahr and
Null Profusion. Can't go infinite either, which I like.
Most monoblue EDH decks can wreck havoc with all their card draws, counters, time walks, rites of replications etc, but I honestly didn't find them that fun to play. They felt too spikey for EDH, I didn't connect to them emotionally or flavorwisely and honestly the games felt a bit too easy to win. :/
