I also think that the classic build is better than Gator one right now. It is always a meta call and the main difference is speed. I first created an Instigator decklist to fight in the Mental Misstep era. Since then it was also awesome when the meta was mostly Stoneforge decks and Maverick. Right now though, I'm in the classic train, but I like dusting off Instigators every now and then to see what they can do in the meta.
Oh, and if you try Instigator, play lots of R sources. 17-19 is what I'd recommend.
Tarfire is not great against Elfrazi, indeed. Even though some take out CotV after SB. removal is not how we win. Board presence and mana denial is.
And I don't agree that Gempalm is better against Delver and Infect. I mean, it is awesome, but so is Tarfire. Post sb we bring in counterable cards. If we don't draw Caverns, our Goblins are counterable. If they Daze your MWM T2, you're gonna have a hard time Gempalming Delver before stabilizing. And regarding Infect, which is a combo deck, paying 1 mana for your removal instead of 2 is HUGE.
All that said, my Classic build now will either play 4 Gempalm/ 1 Tarfire, or a 3/2 split, because the card draw from Gempalm is essential in many other MU's (oh, and 2 Kinesis MD as well because fuck your creatures)
Sounds horrible. Please try it =D
As Olaf said, brainstorming is even more important than the results
@ Olaf:
If you take a look at our DtB, BRx Reanimator is starting to grow in numbers pretty quickly and is a very tough deck. I'm just commenting because some of your SB run both Mindbreak Trap and Thalia, which I think should be wrong nowadays. Thalias + more grave hate can be very good against both Reanimator and Past in Flames deck, and against SnT you have the Thalia + Sting + Needles (Sneak Attack), which I think is both broader and more effective answers.

No, just no. It has been tested.
