(This card is always treated as a "Millennium" and "Gaia The Fierce Knight" card.) If a Level 5 or higher Monster Card is on the field, you can Normal Summon this card without Tributing. The Level of any monster your opponent Normal or Special Summons in Attack Position, while this card is in your Monster Zone, is increased by 7. When your opponent activates a monster effect (Quick Effect): You can send 1 other face-up Level 5 or higher Monster Card you control to the GY; negate the activation, and if you do, destroy that card. You can only use this effect of "Heart of Gaia" once per turn.
Heart of Gaia — Power Evaluation
Final Score: 54 ± 8 · Confidence: Medium
- Intrinsic: 54 · Deck: 53 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Material body
Why it scores here
Heart of Gaia converts its value mainly through a once-per-turn quick effect that negates a monster effect activation, paid for by sending another face-up Level 5+ monster you control to the GY, and through a tribute-free Normal Summon when a Level 5+ monster is on the field. Its 2300 ATK and Level 6 body earn little on their own, since the score comes from the conditional negate and the card's presence in the Exodia and Millennium shells. The negate costs a card and removes one, so it trades evenly rather than generating advantage, and it only reaches monster effects, which keeps the score in the middle band.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Present in all 400 sampled decks with an average of 1.5 copies and high inclusion in two homes (Millennium 66.7%, Exodia 40%), but there is no searcher or searched-for role data, so access is shown by deck presence only (observed). |
| Combo & Conversion | 40 | No recorded boards exist, so conversion rests on the text: a tribute-free Level 6 body plus a conditional negate, with no measured start-to-board line (inferred). |
| Resource Economy | 45 | The negate costs one of your Level 5+ monsters and removes the activated card, so the exchange is roughly card-for-card with no refuel or search (verified from text, inferred for the balance). |
| Effect & Interaction | 60 | The once-per-turn negate stops monster effect activations and destroys the card, and the Level +7 effect hinders opponent Attack Position summons; spells, traps and non-effect monsters are outside it (verified from text). |
| Material Utility | 65 | A Level 6 EARTH Warrior is a clean generic material for Level and Rank 6 summons, and the body still converts when its effects are negated (verified from stats, inferred for conversion). |
| Resilience & Flexibility | 40 | The negate needs another face-up Level 5+ monster and is once per turn, so it goes dark when that condition fails and a single removal ends the body (verified from text). |
| Deck-Building Efficiency | 55 | No garnet or brick restriction, one copy typical, and no self-lock, but it depends on a Level 5+ monster and co-occurs at about 86% with the Exodia and Millennium shell pieces (observed, mild restriction). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Material body. Intrinsic ≈ 54, Deck ≈ 53, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Weaknesses
- Negate requires sending another face-up Level 5+ monster you control to the GY
- Does not stop spells, traps or non-effect monsters

Evidence & gaps
- Verified: Card text: tribute-free Normal Summon with a Level 5+ monster on the field; Card text: once-per-turn quick negate of monster effect activations, costing another face-up Level 5+ monster; Card text: opponent Attack Position summons gain +7 Level while it is in the Monster Zone; Stats: Level 6, EARTH Warrior, 2300/2100; Deck sample: 400 decks, average 1.5 copies, 86% co-occurrence with Exodia pieces; Usage statistics: Millennium 66.7% inclusion (typical 2), Exodia 40% (typical 1)
- Observed: Present in 400 of 400 sampled decks; gameplay type 7 in 69.8% of them; Top partners co-occur at 86-90% with the Exodia and Millennium shell
- Inferred: Tribute-free body has real value in these homes; Negate is roughly card-for-card even; Level 6 body is a generic material
- Data gaps: No combos supplied: combo conversion and starter/searcher roles are text-only inference No guides supplied No banlist token: assumed 3 copies (unlimited) Deck sample may be pre-filtered to decks containing the card (400/400 run it), so inclusion may be overstated Archetype field says Gaia The Fierce Knight, but the deck archetype labels are Millennium and Exodia; text says it is always treated as both 'Destroy that card' target is ambiguous in the evidence text; no rulings supplied
