Hmmm you probably mean the French Championship
I believe in the announcement it was vintage world championships in France, I'm not entirely sure however and changed it to French championships.
Some more points:
I added them, but elaborate the last one. Do you see it functioning as a 5the squee?
Assuming this thread doesn't talk about Restricted cards (the obvious 1-ofs) the metagame potential of unrestricted cards has always been high.
Yes I was talking about unrestricted cards, it was however so obvious in my mind that I forgot to add it. (added it)
Reading the rest of your post I realized I need to define what single cards I am talking about, I am not talking about adding a 5the draw spell to supplement the other draw. I am talking about utility cards that are powerfull enough against certain decks to turn the match up around. (like lava dart in CS vs. CS)
I'm not sure you can criticize or compliment 1-of's without a full metagame breakdown
As I tried to make clear in my original post this thread is not meant to criticize anyone, it is merely a discussion if 1-of's are powerfull enough to be included.
We can all likely name 20 1-of's that could make Dragon or any Bazaar deck better, but we can't name the correct 1 of the 20 that we could choose unless given a metagame to cater to. Also, tuning 3 Chalice + 1-of versus 4 Chalice changes the percentages of consistency versus resilience so it would be quite a project to evaluate each of 20 cards at this pace.
For now this thread is merely a discussion if 1-of's serve a purpose in deckbuilding and if so what that purpose is. When we defined that we might be able to make a list of cards and archetypes they can be used in and against.
I believe the phrase "pretty powerful" and "in particular situations" are kind of ambiguous leading to a meandering argument.
I tried to make it as widely applicable as possible (ie. the 1-of saves your butt in a certain situation no other card could have), but if you want you can change it to powerfull and metagame.
I think that force of will is really good, and it own the metagame right now!
You seem to have no idea what purpose this thread serves, and on top of that its a useless one liner. I would suggest reading the TMD rules.
