Guide for Heroic Atramedes!
Summon many Silver Hand Recruits and use your cheap cards in combos with Acidic Swamp Ooze. Silver Hand Recruit has phenomal value in this fight since it's the only minion you can summon that does not boost Atramedes' weapon. Acidic Swamp Ooze should be saved for a turn when you plan on playing multiple cards. Typically, you'll save these combos for just after he plays Sonic Breath to boost his weapon. As the game progresses, giving Atramedes +1 attack for a high value card doesn't feel so bad. When you have enough Silver Hand Recruits, Quartermaster will provide you a win condition since Atramedes seems to lack full board clears. Note: Many of the cards in this deck didn't see use since he died so early to a board full of 3/3 Silver Hand Recruits. Adjust to your liking.
