Assuming 2 things: Tog needs more acceleration and that Carpet is good, shouldn't people be putting in Sol Ring first (assuming most people are omitting a Sol Ring in favor of Crypt, rather than in addition to) instead of more stuff like Carpet of Flowers? If there is already 5 moxen, Lotus, x Lands, Sol Ring, and Crypt (4 Mana Drains too) how much mana is too much? What do you start cutting? Draw, Search, Togs, Counterspells?
Well, my version of Hulk
does run Sol Ring and Mana Crypt. I think not doing so is incorrect. But that is another topic.
The reason to run Carpet would be:
1. More acceleration. I keep hearing people saying there is going to be too much acceleration in this deck and every time I am surprised. There is such thing as too much acceleration when the acceleration is bad, but if it is good why NOT run it.
2. Color stability against NBLH.
3. Null Rod. This card hurts Hulk a LOT, especially when backed with Wasteland.
At any rate, I think it is testable. What is cut would be an interesting question. It might be Mana Crypt, Sol Ring or Mox Pearl against Fish, to further reduce the effect of Null Rod.
