Quote from Onering »
Expropriate should typically be worse than Time Stretch. Blatant Thievery is a good card, but Time Warp is better, and I'd rather have 2 Time Warps than a Time Warp plus a Blatant Thievery most of the time, especially when the former comes at a lower cost. It's a great splashy card, but it only becomes a problem when someone other than the caster votes for time. That's a problem that you should head off before it resolves by explaining how stupid it is to vote for time. 3+ time walks is usually going to be insurmountable, but a timewalk plus a Blatant Thievery should not be (at least when Time Warp wouldn't win on its own).
I can't agree here.
Time Stretch provides you an additional extra turn, but doesn't steal permanents. I doubt that you can establish as much power in your additional turn on the board as if you steal the best permanents of your opponents. Also, Time Stretch is not a solution, it doesn't remove a threat on your opponents side, Time Stretch can also be a dead card if you don't draw gas after casting it. Expropriate is just so much more of a "I win" card because of the combination of things it does.
ALso, Expropriate is better than Blatant Thievery, because it doesn't target and can steal even the scariest stuff.
Regarding the "but Expropriate is exiled"-argument: 1) if you want extra turn loops, you do not play Time Stretch but one of the cmc5 variants. Also, I have never seen a game where you would even need to use another Expropriate, if it resolves, that it's game over in 99% of cases. It's the very definition of a game ending spell.
I bet that Biorhythm has a lower quote of winning games compared to Expropriate, it's a dead card in many more cases...
