I started by a search for red cards referencing instants and sorceries (both), and went from there. There are 20 creatures and 16 damage-dealing spells, plus 3 copies of Quest for the Pure Flame and 1 of Brain in a Jar. If I can get Charmbreaker Devils into play, I can recycle. It may seem odd that cards such as Chandra's Spitfire are absent, but I didn't want to rely on the damage to deal damage before an attack. All of the creatures enhance or get a boost from damage or casting of the 16 instant or sorcery spells. The 2.28 average comes on a 14/14/6/0/5/1 curve. Yes, those half dozen spells at the top could become an issue, but really only if I faced terrible difficulty in getting going or they all came at once.
