I’ve seen that trick, too. The key is a tighter mana curve – if you’re spending a 2‑cost card at turn one, you’re usually burning your opening hand. You can either play a lower‑cost minion that’s still relevant, or pull a card that reduces cost, like a spell or a minion that makes the next one cheaper. If you want to keep that high‑value minion, make sure you have enough draw to hit it early, or add a card that gives you a card draw every turn. The real efficiency comes from having a consistent, predictable curve that lets you play every card as intended, rather than forcing a 2‑cost to slot into a 1‑cost spot and wasting potential. It takes a bit of deck tweaking, but the payoff is smoother turns and less wasted mana.
