Ursarctic Polar Star

Ursarctic Polar Star — Power Evaluation

Final Score: 47 ± 8 · Confidence: Medium

• Intrinsic: 44 · Deck: 48.6 · Meta: provisional
• Primary role: Combo enabler · Secondary: Floodgate/Control

Why it scores here

The card's main value is an Extra Deck-to-Extra Deck conversion: tributing itself plus a Level 8 Ursarctic monster Special Summons a Level 7 Ursarctic Synchro that ignores summoning conditions and gains this effect, so the card converts two cards into one Extra Deck body. Its own 700 ATK and Level 1 body earn almost nothing, and the 2-monster Synchro-style summon cost makes it card-negative on its own. The deck evidence (in all 400 sampled decks, with 84–100% co-occurrence with Ursarctic partners) confirms the line is live in practice, but it does not by itself confirm power, and the lack of recorded combos keeps the combo axis at inference level.

Axis scores

Calculation

Weight profile: 0.7 Starter/Combo enabler + 0.3 Floodgate/Control. Intrinsic ≈ 44, Deck ≈ 48.6, Meta = provisional. Modifiers: Self-locking restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Converts a Level 8 Ursarctic from hand or field plus itself into a Level 7 Extra Deck Synchro that ignores summoning conditions.
• The Level 7 result gains this effect, so the conversion can continue.
• Live in every sampled Ursarctic deck with near-universal partner co-occurrence, so the route is practical rather than theoretical.

Weaknesses

• Card-negative on its own: the two-monster Synchro-style summon cost plus the tribute leaves a net loss.
• Its 700 ATK and Level 1 body contribute nothing to board or material value.
• Archetype-locked text, so the card has no portability and no value outside Ursarctic.
• No recorded combo boards, so its conversion value is text-only.

Counters / choke points

• Negating the effect after the tribute is paid does not undo the Level 7 summon, but negating before the tribute stops the line cold.
• Removing or bouncing the Level 8 Ursarctic monsters in hand or field shuts the tribute route off.
• Opponent Extra Deck Level monsters are already locked by this card's effect, so the floodgate only partly covers the opponent's board.

Best use

Extra Deck conversion enabler that turns a Level 8 Ursarctic into a Level 7 Synchro that ignores summoning conditions. Decks: Ursarctic. Suggested copies: 1.

Evidence & gaps

• Verified: Cannot be Synchro Summoned; Special Summoned from the Extra Deck by sending a Tuner and a non-Tuner at Level difference 1 to the GY (card text).; Tribute a Level 8 Ursarctic from hand or field plus this card to Special Summon a Level 7 Ursarctic Synchro from the Extra Deck, ignoring its conditions; it gains this effect (card text).; Opponent cannot activate effects of monsters with a Level that were Special Summoned from the Extra Deck (card text).; Present in 400 of 400 sampled decks, average 1.24 copies (deck data).
• Observed: Partner co-occurrence with Ursarctic Septentrion 100%, Big Dipper 99%, Grand Chariot 98.2% (deck data).; Gameplay type 7 in 95.2% of sampled decks (deck data).; Ursarctic archetype inclusion 100% at 1 typical copy (usage statistics).; One guide describes the Ursarctic self-jump line, with the card's role placed in the Level-locked group (guide data).
• Inferred: Primary role is Combo enabler because the text's main effect is an Extra Deck-to-Extra Deck conversion, not a board or removal effect.; Net card loss from the tribute plus self-summon cost (text reading).; Interaction and resilience scores come from the text alone, with no combo or interaction data.; The Level 8 partner requirement limits the route to Ursarctic shells.
• Data gaps: No combos supplied: combo_conversion, resource_economy and the starter/material/payoff split are text-only inference. No banlist token: assumed 3 copies (unlimited). The deck archetype list reports 31 distinct archetypes, which conflicts with the Ursarctic-locked text; the archetype mapping for non-Ursarctic decks is unverified. Duration of the opponent-activation lock is not stated in the text (it is not explicitly limited to while this card is face-up). Only one guide, in Vietnamese, mentions the card, so the human-context signal is thin.
