I recently made a deck centered around the detain mechanic that I considered playing. But I would like to hear some of your opinions about the deck and its playability before I start gathering the cards I don't have. Here is the deck:
It was revealed to me in a dream. All the cards were in my dream except for three slots which I plugged in as Vault Skirge.
FULL DISCLOSURE: The dream was post AVR so there was a copy of Slayer's Stronghold. I decided to keep it pre AVR in my post here.
EDIT: I just remembered. The Skirges might have been 2x Whipflare and 1x something else, probably War and Peace.
EDIT2: Currently 4-0 in my first four games with this. My opponents have been very angry. I fought off a Wurmcoil from Grixis for six turns before I found my second Dispatch. Jeez, I can do a lot of damage.
EDIT3: Streak broken. Lost to an unexpected Overrun. Cracking a Shrine for 10 wasn't enough.
I play a detain deck as well and I always run into a problem against aggro decks. I found that board wipes work quite well in my detain deck. Might want to look into that. The way I see it, you can always detain the big guys that people like to use, their "win conditions." But when you are only detaining 1 to 2 permanents per turn that can be a problem when someone is pumping out creatures rapidly. I found Terminus to work quite well.
