If this card is sent from the hand or field to the GY: You can add 1 Spell/Trap from your Deck to your hand that specifically lists the card "The Winged Dragon of Ra" in its text. You can only use each effect of "Guardian Slime" once per turn.
Guardian Slime — Power Evaluation
Final Score: 57 ± 7 · Confidence: Medium
- Intrinsic: 53.7 · Deck: 59.5 · Meta: provisional
- Primary role: Searcher/Tutor · Secondary: Utility
Why it scores here
Guardian Slime's value is its graveyard trigger: when it is sent from hand or field to the GY, it searches a Spell/Trap that names The Winged Dragon of Ra, which is a repeatable +1 card advantage line inside a single archetype home. Its self-Special Summon needs damage taken first, so it is not a reliable opener, and its battle-phase DEF gain protects only itself. The evidence shows it in every sampled deck and in both recorded combos, but never as starter, searched, or material in those boards, so the high deck inclusion confirms accessibility rather than raw power. Its high deck-building cost-efficiency and resilience across zones keep the score in the mid-50s despite weak interaction and an unproven material role.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Run in all 400 sampled decks at about 2.1 copies each and linked to Winged Dragon of Ra partners, but the hand Special Summon depends on taking damage, so it is conditional (verified deck stats, inferred trigger timing). |
| Combo & Conversion | 45 | Appears in 2 of 2 recorded combos with average power_index 76, yet role_in_combo is empty and it is never tagged starter, searched, or payoff, so the conversion is unconfirmed (observed, inferred). |
| Resource Economy | 60 | The GY-send trigger adds a Spell/Trap search from Deck, a net +1 advantage when it fires, but it is limited to once per turn (verified text, inferred value). |
| Effect & Interaction | 25 | Only a Quick Effect DEF gain during damage calculation on its own battle; there is no negation or removal of opponent cards (verified text). |
| Material Utility | 35 | Level 10 Aqua body, but no recorded boards show it used as material (as_material 0 of 2 appearances), so the material value is inferred from level and race only (inferred). |
| Resilience & Flexibility | 55 | Can be Special Summoned from hand and searched or sent from field to GY, so it is live in more than one zone, but each effect is once per turn and it is a single body (verified text, inferred). |
| Deck-Building Efficiency | 70 | Runs up to 3 copies in 400 decks with no garnet or lock restriction; the only data gap is the missing banlist token, assumed unlimited (observed deck stats, verified). |
Calculation
Weight profile: 0.7 Searcher/Tutor + 0.3 Utility (default). Intrinsic ≈ 53.7, Deck ≈ 59.5, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Graveyard-triggered search for Winged Dragon of Ra Spell/Traps gives repeatable card advantage inside its home archetype
- Present in every sampled deck at 2 to 3 copies with strong partner co-occurrence
- Clean deck-building cost with no garnet or lock restriction
Weaknesses
- Hand Special Summon requires taking damage first, so it is not a reliable opener
- Only protects itself with a DEF gain; no negation or removal
- Material role is unproven in recorded boards
- Most of its deck presence sits in two closely related archetype homes
Counters / choke points
- Opponent can negate the GY-trigger search or the once-per-turn effect with a hand trap or Spell/Trap effect (inferred)
- Banishing or removing it from the GY before the trigger resolves stops the search (inferred)
Best use

Evidence & gaps
- Verified: GY-send trigger searches a Spell/Trap naming The Winged Dragon of Ra; Hand Special Summon requires taking battle or effect damage; Quick Effect DEF gain in damage calculation only; Present in 400 of 400 sampled decks, avg 2.12 copies
- Observed: Appears in 2 of 2 recorded combos with average power_index 76; Partners with Winged Dragon of Ra cards in 85 to 94 percent of decks; Inclusion 100 percent in the Winged Dragon of Ra archetype
- Inferred: The GY search is a net +1 card advantage when it fires; Material value comes from Level 10 Aqua fit; Resilience comes from multi-zone access with once-per-turn limits
- Data gaps: no banlist token, assumed 3 copies (unlimited) combos_evidence has only 2 boards, so combo role is thin role_in_combo is empty for both examples no per-card ruling data for timing interactions
