Common Strategic Errors

Overconverting

Before activating an outlet, ask: What is the next scoring event? Which unit survives to it? What battlefield am I conceding? What is the premium Hook hit rate from known zones? Can the opponent disrupt the conversion? What Power remains after resolution?

• Playing Karthus without immediate value — a setup-sensitive engine, not a curve obligation.
• Hooking a three-Might unit as though the deck has four-Might payoffs. It does not.
• Treating Hook as a guaranteed Dragon — the six-Might premium rate is closer to 59% before conditioning, not 100%.
• Copying a play-trigger unit for its play trigger — Harnessed Dragon, Watcher and Ashe do not work that way when copied.
• Copying Herald with the Legend when the movement trigger is the desired effect — use Mirror Image for base starts.
• Forgetting Power after Herald dies — Energy is ignored, Power is not.
• Using Dusk Rose Lab before verifying the Hold — the Lab triggers before scoring.
• Spending Dragon Form too casually — it is both a Hook bridge and a recoverable Legend discard through Flow.
• Using Temporal Breach as unconditional removal — the opponent replays the card and may receive its play trigger again.
• Bringing too many spells from the sideboard — diluting unit density directly weakens Hook.
• Casting Ruination without a reconstruction plan — Deathknells alone do not make the reset asymmetric; you need the right hand, Power and trigger order.
