Ameba — Power Evaluation
Final Score: 40 ± 8 · Confidence: Medium
- Intrinsic: 40.3 · Deck: 39.7 · Meta: provisional
- Primary role: Utility · Secondary: Material body
Why it scores here
Ameba is a 300-ATK Level 1 body whose only text is a reactive punisher: when control of it shifts to the opponent, it deals 2000 damage, once while it stays face-up. The score comes from its low-cost, one-copy deck slot and its use as a generic Level 1 material, not from its stats. The 2000-damage effect only matters if the opponent takes control of it, which the evidence does not show happening often, so it earns little interaction or combo credit.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 40 | Appears in 18 recent decks at one copy each across 9 archetypes, but there are no searchers or combo starts in the evidence, so it is only a live body when drawn (observed; inferred for the rest). |
| Combo & Conversion | 15 | No recorded combo boards (0 appearances); its only conversion is the control-shift damage, which needs the opponent to take control of it (verified text; no combo observation). |
| Resource Economy | 10 | No draw, search, refuel, or recursion text, and it is a single body with no card advantage (verified). |
| Effect & Interaction | 30 | Its 2000-damage punisher deters or punishes control-change plays, but it is situational and needs the opponent to act first (verified text; inferred for the deterrent value). |
| Material Utility | 40 | Level 1 WATER Aqua with no tuner text, so it is a usable generic material whose value does not depend on its effect (verified stats; inferred for Synchro/Xyz use). |
| Resilience & Flexibility | 20 | A 300-ATK face-up body with no protection; one removal or banish ends its effect, and its punisher only works while face-up (verified text; inferred). |
| Deck-Building Efficiency | 90 | One copy in every observed deck, no garnet, no lock, and no restriction; it is a cheap, clean slot (observed). |
Calculation
Weight profile: 0.7 Utility + 0.3 Material body. Intrinsic ≈ 40.3, Deck ≈ 39.7, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap, clean one-copy slot that fits into many archetypes
- Usable generic Level 1 material
- Punishes an opponent who takes control of it, for 2000 damage
Weaknesses
- Its main effect only fires if the opponent gains control of it, which the owner cannot cause on purpose
- A 300-ATK body dies to any removal or banish
- No searcher, draw, or combo role in the evidence
Counters / choke points
- Keeping control-change effects off the board so the 2000-damage trigger never fires
- Removing or banishing the body outright
Best use
Utility body with a control-steal punisher. Decks: Thunder Dragon, Dark Magician, Frog, Sacred Beast. Suggested copies: 1.
Evidence & gaps
- Verified: Text: 2000 damage when control of this face-up card shifts to the opponent, once while face-up; Level 1 WATER Aqua, 300 ATK / 350 DEF, no link or pendulum; Legal in TCG, OCG, MasterDuel, and DuelLinks; 1 copy in each of 18 decks, 0 side-deck copies
- Observed: Present in 18 recent decks across 9 archetypes (14 in format 7, 4 in format 4); Top partners are common staples (Magic Cylinder, Dark Magician, Greater Polymerization) at 55–67% co-occurrence
- Inferred: The punisher is a deterrent rather than a reliable source of damage, since the owner cannot force a control change; Generic Level 1 body that is useful as material for Synchro/Xyz; Inclusion reflects generic slot use, not intrinsic power
- Data gaps: No combos supplied, so combo conversion and deck synergy are text-only inference No guides supplied No frequency data on how often control-change effects appear in these formats No banlist token; assumed 3 copies (unlimited) No usage statistics (StatisticsCard); archetype inclusion inferred from the 18-deck sample only
