Therion Irregular — Power Evaluation
Final Score: 66 ± 6 · Confidence: Medium
- Intrinsic: 64 · Deck: 67 · Meta: provisional
- Primary role: Board breaker · Secondary: Recovery/Recursion
Why it scores here
Therion Irregular's value comes from its opponent-field wipe, which turns a single discard of Endless Engine Argyro System into destroying every card the opponent controls, and from its ability to be hand-Special-Summoned and to pull up to 3 Therion monsters from the GY as equips. The combo evidence supports this: it appears in all 6 recorded boards, mostly as an end-board piece, with a power index of 100 and net card advantage of 5 to 8. The 1600 ATK and 2800 DEF earn nothing by themselves, and the body's material value is only moderate. The score is held down by the Argyro discard cost, the Therion-only text, and the thin combo sample.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 70 | Hand Special Summon with no stated cost, and it is live in the opening hand, but the wipe needs Argyro in hand (Argyro is in 47% of decks). (inferred) |
| Combo & Conversion | 80 | Appears in 6 of 6 recorded boards, end-board appearances in 3, with average power index 100 and 3 to 4 end monsters on the examples. (observed) |
| Resource Economy | 70 | Equipping up to 3 GY Therion monsters refuels the board, and the examples show net card advantage of 5 to 8, offset by the Argyro discard. (verified text, observed) |
| Effect & Interaction | 75 | Destroy-all-opponent-cards is a strong sweep, but it needs an Argyro discard and has no negation or hand-trap reach. (verified) |
| Material Utility | 55 | Level 10 Machine DARK is a generic body with no Tuner, and the material conversion is only shown in 1 of 6 combos. (verified, observed) |
| Resilience & Flexibility | 55 | Can Special Summon itself and re-equip while equipped, giving multi-zone and multi-turn value, but one negate on the wipe ends it. (verified text, inferred) |
| Deck-Building Efficiency | 45 | Demands the Therion archetype plus Argyro, a committed build with a card dependency that restricts the deck. (observed) |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Recovery/Recursion. Intrinsic ≈ 64, Deck ≈ 67, Meta = provisional. Modifiers: Argyro discard dependency (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Destroys all opponent cards for a single discard, with a high end-board rate in recorded combos (power index 100)
- Hand Special Summon plus GY equip gives it recursion and refuel
- Shows up in 100% of the sampled Therion decks, and the Therion archetype accounts for 43% of them
Weaknesses
- Needs Argyro in hand for the wipe, which is a card-specific dependency
- Archetype-locked text, so it does not travel to other homes
- Thin combo sample (6 boards), so the power read is provisional
Counters / choke points
- Negation of the wipe effect in response to activation
- Opponent recovery or re-summon after the field is destroyed
Best use
Board breaker and end-board finisher with GY-equip refuel. Decks: Therion. Suggested copies: 1.
Evidence & gaps
- Verified: Hand Special Summon, GY targeting up to 3 Therion monsters with equip, and the opponent-field destroy effect with the Argyro discard, all from card text; Level 10 Machine DARK, ATK 1600, DEF 2800, and each effect once per turn, from card text; Appears in 400 of 400 sampled decks, with 100% partner rate for Therion "King" Regulus
- Observed: In all 6 recorded combos, 3 as end-board appearances and 1 as material; Average power index 100 and net card advantage 5 to 8 on the examples; Inclusion of 73.7% in the Therion archetype in the usage statistics
- Inferred: Live in the opening hand because it is hand Special Summonable with no stated cost; Wipe route is practical because Argyro is in 47% of decks; Secondary Recovery role from the GY-equip and self-revival
- Data gaps: No banlist token, so 3 copies are assumed legal Only 6 combos, so the combo evidence is thin No rulings data The guide evidence is Duel Links context, so it may not match the TCG or OCG text
