Form of the Dragon - Foil

Although expensive and it has that nasty little drawback, you can easily kill your opponent before they get a five power flier through.

With Cards like: Pariah (especially if used on something like Cho-Manno Revolutionary, stuffy doll, OR you can just use it on whichever the most powerful creature YOU DON'T CONTROL happens to be), Spirit of the Hearth (Which basically gives You Shroud), Moonhold (is good if you're opponent doesn't have a flier yet but is about to get one into play), You could also try Firespout or Raking Canopy to specifically target flying attackers (; but neither will kill a 5/5 flier by itself).

sounds over rated. Puts you in a tight spot.

great card, but very, VERY vulnerable to either shooters or "destroy target enchantment" effects. Especially now with the revived Domain mechanic, this card is really on shaky ground.
Example:
You: "I play Form of the Dragon and pass."
Me: "I shoot you for 5 with Tribal Flames and win."

Still, I love the artwork and the "Creatures without flying can't attack you" combined with the "My turn, I burn you for 5" concept, but being stuck on 5 life is really harsh unless you play with Convalescent Care (now THAT'S what I call kickass in a red/white burn deck!
