Send 1 "Therion" card from your Deck to the GY. If this card is in your GY: You can target 1 "Therion" card in your GY; if both are still in your GY, add either that card or this card to your hand, and if you do, place the other on the bottom of your Deck. You can only use 1 "Endless Engine Argyro System" effect per turn, and only once that turn.
Endless Engine Argyro System — Power Evaluation
Final Score: 53 ± 6 · Confidence: Medium
- Intrinsic: 50 · Deck: 55 · Meta: provisional
- Primary role: Recovery/Recursion · Secondary: Searcher/Tutor
Why it scores here
The card's value is recursion: from the GY it adds itself or a second Therion to hand, sending the other to the bottom of the Deck, once per turn. It converts a GY card into a hand card, but it needs a Therion already in the GY and a Therion sent from the Deck first, so it is dead without that setup. The 100 power index on its boards and the 400/400 deck inclusion reflect a strong Therion shell, not an intrinsically powerful effect, so they lift the Deck term only modestly. Its 5/100 interaction and material scores mean its ATK, DEF and effect count earn nothing.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 62 | Needs a Therion in the Deck to send and a second Therion in the GY to recur; the shell is near-universal (400/400 decks), but the card is not live from the opening hand alone (observed, inferred). |
| Combo & Conversion | 60 | Present in 6/6 recorded combos with average power index 100, yet only 1 starter and 1 end-hand appearance, so it is a support piece in the boards rather than their trigger (observed). |
| Resource Economy | 72 | Recovers one GY card to hand while the other goes to the bottom of the Deck, and the Deck-to-GY Therion send fuels the GY; this is repeatable only once per turn (verified from card text, observed via netCardAdvantage 5-8). |
| Effect & Interaction | 5 | No negation, removal or hand-trap effect in the text (verified). |
| Material Utility | 5 | A Spell card that is never used as Extra Deck material, so the body provides no material value (verified from card text). |
| Resilience & Flexibility | 45 | Works only from the GY, once per turn, and depends on two Therions being there; redundancy comes from the large Therion pool (inferred from text and deck archetypes). |
| Deck-Building Efficiency | 45 | Costs a slot in a Therion-restricted deck with 1.62 average copies and no banlist token, so it is cheap to run only inside that shell (observed from copies per deck; restriction inferred). |
Calculation
Weight profile: 0.7 Recovery/Recursion + 0.3 Searcher/Tutor. Intrinsic ≈ 50, Deck ≈ 55, Meta = provisional. Modifiers: Self-locking restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Turns a GY Therion into a hand card once per turn, with the second card recycled to the bottom of the Deck.
- Its effect is cheap to run, with 1.62 average copies per deck.
- It appears in every recorded Therion-shell deck and in all six sampled boards.
Weaknesses
- Needs a Therion in the GY and one sent from the Deck before it does anything.
- Once per turn, and it cannot interact with the opponent.
- Narrow to the Therion archetype; the other 54 archetypes in the sample are incidental inclusions.
Counters / choke points
- Graveyard hate or GY-recursion denial will shut off the only effect, which works only from the GY.
- Opponent interaction does not target this card in the text, so there are no extra counter routes beyond GY hate (inferred).
Best use
Once-per-turn GY recursion that returns itself or a second Therion to hand, with the other sent to the bottom of the Deck.. Decks: Therion Discolosseum shells, Therion "King" Regulus lines. Suggested copies: 2.
Evidence & gaps
- Verified: Once-per-turn GY recursion: adds itself or a Therion to hand, sends the other to the bottom of the Deck.; The Deck-to-GY Therion send is the entry cost.; No opponent interaction or material effect in the text.
- Observed: Present in 400/400 decks with 1.62 average copies.; Appears in 6/6 recorded combos, with 1 starter and 1 end-hand appearance.; Average power index of 100 on boards it appears in.
- Inferred: Requires a Therion in the GY and one sent from the Deck before it works.; Its redundancy depends on the size of the Therion pool.
- Data gaps: No banlist token; assumed 3 copies (unlimited). No usage statistics (StatisticsCard); archetype inclusion % is inferred from the deck sample only. Only 6 combos recorded, so combo conversion rests on a small sample.
