Template:Forbidden Shaping strategy
Forbidden Shaping is flexible, usable both as an early game play (in the case that you don't draw normal early game cards) and as a late game threat, depending on draws and matchup. It should be kept in mind, however, that the minions summoned could be suboptimal, such as 
Faceless Shambler, or extremely harmful to the current board, like 
Doomsayer.
The best amount of mana to play Forbidden Shaping at, as of Whispers of the Old Gods, is 8. The reason is because there are no conditional minions available, like 
Acidmaw at 7, or Alexstrasza at 9. While you could also play it at 10 to get a 12/12 Deathwing or Deathwing, Dragonlord, you could also get a normal 8/8 Giant, a 7/7 Varian Wrynn, or, at worst, an unbuffed 6/6 C'Thun.
Used at 8 mana, most minions are average, like 
Fossilized Devilsaur, and the worst minions, The Boogeymonster, are still usable. Others such as Tirion Fordring or Ragnaros the Firelord provide excellent value.
The single biggest fallback, or biggest advantage, of playing Forbidden Shaping on 8 mana, is that you could get Anomalus, which can singlehandedly destroy your board, or completely ruin the opponent. Dealing 8 damage to all minions is almost always the same as Twisting Nether, but as a Deathrattle.
