This one can be easily obtained by playing as Silent, it is almost automatically gotten if the deck is based on Shivs, in fact, Blade Dance+, which is a upgraded common card, gives you 5 played cards for 1 Energy only. Common Energy Potion is 2 Energy.
I'm pretty sure everyone who played Silent on Shivs got this achievement.
So, what's needed:
- 4+ copies of Blade Dance+ (Toxic Egg relic is perfect, but without it those can be done, too);
- some relics for Energy or Energy Potion;
- some cards to find Blade Dances+ (Prepared and Calculated Gamble are the best)
-- or Duplication Potion,
-- or Swift Potion;
- some 0 Enegry's cards (again, Prepared and Calculated Gamble are very useful).
