Agreed. That said:
There seems to be a distinct two-part element to all successful anti-FG decks:
1) Establish a mechanism by which to stay alive
2) Establish a win condition
The simplest (and original) anti-FG deck, the mono-aether beatdown, did this in the simplest possible way: slap up Dimensional Shields to stay alive while Phase Dragons provided the win. This deck barely works at all anymore, because it seems like almost every FG is set up with either a way to ignore your shields (Explosion/Steal/Momentum) or a way to outlive your damage (Miracle, Bonds, Black Holes).
So the standard rainbow deck comes with a HUGE variety of ways to establish your continued life: Oty+Firestorm+Bone Wall, Permafrost+SoG, Bonds+Graveyard+FFQ, and of course those mix-and-match quite well.
On the other hand, the standard rainbow deck doesn't have too many tricks up it's sleeve for actually killing the FG. Fallen Druids make Mutant Swarms, and if something screws that up, you're stuck relying on one big Otyugh and a swarm of Fireflies...which doesn't always cut it.
Alternate FG decks like Yaladilae's Poison Quartet (
http://elementscommunity.org/forum/index.php/topic,5725.0.html) utilize a profound alternate method of winning (poison buildup) while using a strong defense (Permafrost+Inundation+SoGs), with a strong counter-defense (Anubis+Quint) but they still go through the same phases -- namely, you draw madly and struggle to survive the onslaught until you get your defenses up, then you keep drawing until you establish the Fractal+Chrysora+Anubis = Immortal Chrysora win condition.
The point here is that, when considering any anti-FG build, you have to start by asking yourself "How am I going to survive?" -- then ask "How am I going to win?". There are relatively few ways to answer that first question:
Massive healing (Bonds+swarms, Miracle+Stone Skin)Permafrost (Dusk Mantle/Procrastination/Diamond Shield)+Strong HealingDissipation Shield + Massive QuantaHope+Lots of Light-producing creaturesStacked Dimension Shields (+Sundials?)
Feel free to mention any I've missed.
Basically, your goal as an anti-FG deckbuilder is to find some win condition that you can pair with one of the above methods of staying alive. Oh, and it helps a lot if you can work some counter-defense (
