Each time a face-up "Mythical Beast" Pendulum Monster Card(s) you control is destroyed by battle or card effect, place 2 Spell Counters on this card. Once per turn: You can remove any number of Spell Counters from your field; add 1 monster to your hand from your Deck or face-up Extra Deck, with a Level equal to the number removed, that you can place a Spell Counter on. If this card on the field would be destroyed by card effect, you can remove 1 Spell Counter from this card instead.

Why it scores here
Mythical Institution is a core consistency piece for Endymion and Mythical Beast decks, running at 100% inclusion in Endymion with 3 typical copies. It reliably generates Spell Counters from Mythical Beast Pendulum destructions and tutors specific monsters to maintain combo lines, enabling the deck's engine-heavy playstyle. However, it is not searchable itself, contributes zero offensive interaction, and depends entirely on its archetype home to function, capping its flexibility and resilience.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 75 | Runs at 100% inclusion in Endymion decks with 3 typical copies, but requires being drawn since it is not searchable; confirmed by deck statistics showing 162/400 decks maxing copies (verified). |
| Combo & Conversion | 60 | Fuels the Spell Counter engine by converting destroyed Mythical Beast Pendulums into searched monsters, but is primarily a support piece rather than a board starter; no combo data supplied, so inferred from text and deck synergy (inferred). |
| Resource Economy | 65 | Generates multiple Spell Counters per Mythical Beast destruction and enables deck thinning via searches; self-protection extends its lifetime and efficiency (inferred). |
| Effect & Interaction | 5 | Has zero offensive interaction—no negation, removal, or disruption; only defensive self-protection via counter removal (verified). |
| Material Utility | 0 | Is a Continuous Spell and cannot serve as synchro, XYZ, fusion, or link material; contributes no material value (verified). |
| Resilience & Flexibility | 70 | Persists as a live Continuous Spell across turns and protects itself via counter removal once per effect destruction; however, inflexible outside Mythical Beast/Endymion themes and vulnerable if the Mythical Beast engine is disrupted (inferred). |
| Deck-Building Efficiency | 65 | Requires no deck restrictions or lock effects, and its 3-copy inclusion in Endymion suggests efficient slot usage; however, entirely theme-dependent and not splashable (observed). |
Calculation
Weight profile: Primary role: Searcher / Tutor (single primary role). Intrinsic ≈ 57, Deck ≈ 63, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Core consistency piece in Endymion and Mythical Beast decks (100% inclusion in Endymion).
- Generates multiple Spell Counters from natural Mythical Beast Pendulum destruction.
- Flexible search effect: any Level, any monster in Deck/Extra Deck with counter-placeable.
- Self-protective against one card-effect destruction per activation (removes counter instead).
- Enables the Spell Counter engine that powers Endymion/Mythical Beast board development.
- Typical 3-copy inclusion in Endymion suggests efficiency within the archetype.
Weaknesses
- Not searchable—must be drawn or set in opening hand.
- Requires Mythical Beast Pendulum monsters on field to generate counters.
- Zero offensive interaction: no negation, removal, or disruption.
- Entirely inflexible outside Mythical Beast and Endymion themes.
- Vulnerable if Mythical Beast engine is disrupted early or board is cleared.
- Does not generate card advantage on its own; relies on searched monsters to create value.
Counters / choke points
- Spell activation negation (e.g., Ash Blossom on the search effect).
- Spell removal before counters accumulate (e.g., Cosmic Cyclone, Harpie's Feather Duster).
- Hand traps that stop Mythical Beast summons or effects (e.g., Effect Veiler prevents destruction and counter generation).
- General disruption of the Mythical Beast engine (e.g., Synchro Killer, Pendulum lock effects).
Best use
Searcher / Spell Counter resource engine. Decks: Endymion, Mythical Beast.
Evidence & gaps
- Verified: Card text is complete and clear: generates 2 Spell Counters per destroyed Mythical Beast Pendulum; searches monsters from Deck/ED with Level equal to counters removed; self-protective (remove 1 counter to avoid destruction).; Runs in 400 decks; 100% inclusion in Endymion (arch 175), 26.2% in Mythical Beast (arch 890).; Top co-appearance cards are all core Endymion/Mythical Beast engine pieces: Servant of Endymion, Mythical Beast Jackal King, Endymion Mighty Master, Selene (all 99%+).; Usage statistics confirm 100% typical inclusion in Endymion with 3 copies, 50% in Mythical Beast with 2 copies.; Not banned; assumed unlimited (3 copies legal).; Is a Continuous Spell—not a monster, so zero material utility.
- Observed: Deck inclusion is 100% in Endymion, 26.2% in Mythical Beast, fringe in 14 other archetypes.; Average copies per deck: 2.06; distribution: 137 decks at 1 copy, 101 at 2 copies, 162 at 3 copies.; Recency confirms recent inclusion (latest 2026-09-28, earliest 2025-01-05).
- Inferred: Primary role is Searcher/Tutor: the core function is removing counters to search specific monsters from Deck/Extra Deck.; Secondary roles: Combo Enabler (fuels the Spell Counter generation engine) and Resource Economy (self-sustaining via natural destruction of Mythical Beast Pendulums).; Accessibility is high in core homes due to 3-copy inclusion, but not searchable (must be drawn).; Resilience is moderate: persistent on field across turns and self-protective once per destruction, but entirely dependent on Mythical Beast engine.; Deck synergy is core to Endymion/Mythical Beast identity; 100% inclusion in Endymion indicates essential consistency role.
- Data gaps: No combo data supplied: combo conversion is text-only inference, not observed from combo boards. No explicit banlist token provided: assumed unlimited (3 copies legal). Sky Striker and Spellbook homes (9.5% and 4.5% of decks) underdeveloped—unclear if Institution is core or tech in these archetypes. No counter/interaction evidence supplied: counters are inferred from card mechanics and common YGO disruption patterns.
