Early game, you want to have one or two basic lands and an Izzet Boilerworks for lands. You're gonna need probably a Rift Bolt or Lightning Bolt to remove smaller, preferably flying creatures, because, as you may have noticed, this deck lacks flying creatures. If your hand has Desperate Ritual or Seething song, don't do this, but if you don't have them, discard a larger spell (something like Volcanic Awakening) using Frantic Search or Faithless Looting to draw two cards. You will also want a Goblin Electromancer to lower down the costs of your other, more powerful spells. It is at this time that you want to cast cheaper creatures like Young Pyromancer. For now, you're stalling.
