You also need to make sure you hit your land drops, either with draw effects (Qiqirn Merchant and Adventurers Airship provide usable bodies as well as draw smoothing) or cards that directly give you lands or mana (World Map, landcyclers, Blitzball)
As of this writing, theres no word as to whether Lorcana cards will be sold at big box stores like Target or Wal-Mart, but stay tuned

Protect your characters with Aurora Dreaming Guardian Although the most popular Sapphire/Steel deck runs Cogsworth, Aurora is actually more useful in many situations than Cogsworth

Prerequisites: Hullbreaker Horror and Sol Ring are on the battlefield
