Gust Jinn and King Seahorse allow you to send the specific card you need, but you must have it in your hand first. Chappie the Ghost does the same, but fetches it from the deck instead.
Use Hades Steersman to maintain power advantage. When you ride a Grade 3 unit into your vanguard circle, you could revive Steersman then retire it to revive a Grade 1 unit (Samurai Spirit or Deadly Nightmare). This would result in a 20000 Attacking Dragon Undead with ONLY using Counterblast 2 (using Steersman to revive a Grade 1 unit behind Dragon Undead.)
