I completely disagree. While people didn't run these cards in the appropriate context, He also loses to:
* Field of Ruin
* Rishadan Port (you port him every turn and if you have a threat you win)
*
Hex Parasite,
Damping Sphere, Pithing Needle, and similar cards turn his deck off. If you have any two of those (or similar effects) his deck is hosed (as are all storage land decks. Some of these obviously hit other interesting things)
* Cavern of Souls + good threat (it takes 7 turns for confiscate to turn on. A 3/3 or better wins you the game OTP)
*
Skylasher - you just win the race because he can't do anything until turn 5; in which case you already have 10+ damage on him.
*
Mistcutter Hydra and any strategy that makes him 2/2 or larger.
* etc (probably dozens of other cards)
If you lose to a storage land Force-Griffon deck now that we see it's an effective strategy; it's your own fault IMO. There are many ways to hate on it (colorlessly to boot) that one should simply expect to run a card that gets through.
Many of the above cards are relevant in other situations as well, such as blowing up tabernacle, tapping down a combo-deck's land, removing counters from the "vertical growth" style cards, hosing double-mana lands, etc.
I think people are too 'ban-happy' right now. We've had exactly one round so far. Let's ride it out for at least a second round
EDIT: More fun cards to consider
Suppression Field,
Alpine Moon,
Boseiju, Who Shelters All,
Meekstone, etc
You can run something dumb like Meekstone, Alpine Moon, Mountain, Mishra's Factory. Bam. You just won against 100% of Force + Griffon decks; most man-land decks; most "beater" decks, and many combo decks (due to land-screw.)
