Psychic venom against Dragon does not work: when their land is removed from the game from the CiP effect of the dragon, your enchantment drops. It is only their permanent which are removed from the game, and you are still the controller of the Psychic venom...

At best, they will take 2. Nice try, same player shoot again

Regarding deck ranking, I am investigating the use of ELO system to rank deck and not people. It requires some hypothesis, but it is feasible and it shows some promising results. The only issue - but it is a big one -is getting results match by match and not only the top 8.

At the end, you end up with a ranking giving you the best "overall" deck. Of course, like all mathematic-based solution, it requires a certain amount of data to give a good representation of the meta-game.

I agree that this list can expand a lot and vary according to your play style, but I am very interested in this list as I am constantly trying to build different (netdeck or not) decks.
I think this list should be used as "What should I have if I want to play any deck in a 10 proxy tournament". Once you cut the ten most expansive/rare cards of each type one deck, you will end up with quite an extensive list, but very affordable.

To expand the list with the latest deck:
3 Mindslaver
1 Pentavus
1 Platinum Angel
3 Guilded Lotus (or not depending on your version)
4 Thirst of Knowledge

Old fashioned deck:
Rector-Trix:
3 Illusions of Grandeur
2 Donate

Since your deck is white based first and you have trouble reaching sometimes UU, would you consider playing 3-4 Academy Rector and only one Zur's Weirding ?
Against Agro deck, Academy rector is as good as Moat, since they really have to think twice before killing one.
At the same time, it will allow you to play one Future Sight and one Yawgmoth's Bargain.
Since the Rector definitely help against aggro deck, to squeeze four of them, I would do something like:
-4 Swords/Exalted Angel (since they are more efficient against aggro)
-2 Zur's Weirding (it is dead after the first one is in play)
+4 Academy Rector
+1 Future Sight
+1 Yawgmoth's Bargain.

The other advantage is that the second Zur's Weirding is dead, whereas the second Academy Rector can go fetch Future Sight or the Bargain.

It also allows you to have more silver bullet in the sideboard (Form of the Dragon for example - nice synergy with the Weirding as you will always replenish your life).

By the way, I don't know if Pursuit of Knowledge is a win more card or a nice way to break the symetry of the Weirding. Since it is a replacement effect, you forgo the next three draw phase, then you can draw 7...

That's my tiny contribution. By the way, I have to admit I am speaking without having tested the deck
