Mythical Beast Jackal King

Mythical Beast Jackal King — Power Evaluation

Final Score: 73 ± 5 · Confidence: Medium

• Intrinsic: 70 · Deck: 71 · Meta: provisional
• Primary role: Negation/Interaction · Secondary: Extender, Material body

Why it scores here

Mythical Beast Jackal King is a core defensive piece in Spell Counter-based decks, particularly Endymion, where it appears in 100% of archetypes at 3 copies. Its quick-effect monster negate powered by Spell Counters provides reliable interaction, while its Pendulum effect enables Extra Deck summoning in pure Pendulum lines. The card's strength lies in its resource efficiency within Spell-heavy environments—Spell activations feed its negation ability—and its accessibility across 28 archetypes as a searchable, splashable body. However, without combo data, the full extent of its combo conversion cannot be verified, and it remains primarily a supportive interaction piece rather than a pure engine card.

Axis scores

Calculation

Weight profile: 0.7 Negation/Interaction + 0.3 Extender. Intrinsic ≈ 70, Deck ≈ 71, Meta = provisional. Modifiers: splashability (2). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Highly accessible via multiple searchers (Servant of Endymion, Mythical Beast Jackal, Selene QMM) and runs 2-3 copies with strong redundancy
• Quick-Effect monster effect negate is one of the highest-quality interactions, providing reliable disruption against combo-focused opponents
• Excellent resource efficiency in Spell-heavy decks: each Spell activation auto-generates 2 counters, powering the negate at low cost
• Splashable across 28 archetypes, not limited to a single home; even off-theme decks like Sky Striker (9.2%) and Spellbook (6%) run it
• Dual role as both Pendulum body for setup and reactive negation engine provides flexibility across different game states

Weaknesses

• Combo conversion is entirely dependent on deck environment; without Spell support, the monster effect is slow to power up
• Monster effect only negates opponent effects, providing no offense or forward momentum on its own
• Pendulum effect requires the other Pendulum Zone to be empty and destroying itself, limiting its use as a pure combo starter
• Counter generation is passive (triggers when opponent's Spells resolve), making the negate slower to set up on your turn
• Against non-combo decks or strategies that avoid monster effect activation, the monster effect becomes largely irrelevant

Counters / choke points

• Ash Blossom & Joyous Spring (hand trap that stops searchers like Servant of Endymion, preventing deck setup)
• Prohibition-effect cards naming Mythical Beast Jackal King or key Mythical Beast pieces
• Decks that avoid monster effect activations (control-oriented strategies) reduce the negate's relevance

Best use

Defensive negation engine with Spell Counter synergy. Decks: Endymion, Mythical Beast, Spellbook, Odd-Eyes, Solfachord. Suggested copies: 3.
