A Time-Boxed ("Until the End Phase") Control Grant Holds Even Against an Opponent's Continuous Control-Take Equip

When a monster is already under a continuous control-take effect (an Equip Spell that says "while [condition], take control of the equipped monster") and a lingering, time-boxed control-take effect ("you can take control of that monster until the End Phase") then takes it from the other player, the time-boxed grant holds control for its full stated duration. The continuous equip does not snap control back the instant the chain resolves or the next game-state check happens. Control only returns to the continuous equip's controller at the time-boxed grant's stated end point (the End Phase) — and only then if the continuous equip's own condition is still being met.

This settles a question that the Continuous Application Effects framing alone does not answer: that file establishes that continuous effects are constantly re-checked, which by analogy (see Mind Control-style takebacks) suggested the continuous claim should immediately re-assert. The actual official ruling for this specific pairing goes the other way — the newer, explicitly-durationed grant is respected for its full duration before the continuous claim resumes.

The cards

Sky Striker Mecha - Widow Anchor (Quick-Play Spell) — "If you control no monsters in your Main Monster Zone: Target 1 face-up Effect Monster on the field; negate that face-up monster's effects until the end of this turn, then, if you have 3 or more Spells in your GY, you can take control of that monster until the End Phase."

Mikanko Reflection Rondo (Equip Spell) — "Equip only to an opponent's monster. While you control a 'Mikanko' monster, take control of that equipped monster. Neither player can activate the effects of the equipped monster while you control it. When this card leaves the field, send the equipped monster to the GY. You can only control 1 'Mikanko Reflection Rondo'. You can only activate 1 'Mikanko Reflection Rondo' per turn."

Mikanko Reflection Rondo's control-take is a continuous, condition-gated effect — no colon-gated trigger, no stated end point, just "while X, take control." Widow Anchor's control-take is a one-time, lingering grant with an explicit stated duration ("until the End Phase").

The ruling

Verdict: Widow Anchor's controller keeps the monster until the End Phase. Mikanko Reflection Rondo's continuous claim does not immediately reclaim it mid-turn, even though Rondo's condition (its controller still controls a "Mikanko" monster) remains true throughout. Only at the End Phase, when Widow Anchor's grant expires on its own terms, does control revert — and at that point Mikanko Reflection Rondo's continuous effect resumes applying, putting the monster back under the Rondo controller (assuming Rondo is still face-up and its condition still holds).

This was genuinely contested at the community-judge level before being settled: judges in the TCG community disagreed over whether the newer lingering grant or the older continuous claim should govern, with one judge initially arguing for Anchor and self-correcting to Rondo before the discussion was pushed back on again. The interaction is not covered by a published Konami DB Q&A or a Yugipedia rulings page (Widow Anchor's rulings page is incomplete on this point, and Mikanko Reflection Rondo's Konami DB entry has no relevant Q&A). It was resolved via a direct, official email ruling from Konami's judge program rather than a public Q&A posting.

Confidence note: treat this as an officially-settled answer for this specific pairing, sourced to a judge-program email rather than a public Konami Q&A page. Because there is no public citation to point a player to, tell them the answer is correct but is sourced to an official ruling email rather than a public database entry if they ask for a link.

Why this isn't just "continuous effects always win"

Do not over-extend this single resolved pairing into a blanket rule that "a stated-duration control grant always beats a continuous control-take," or the reverse. TCG continuous-effect interactions are sensitive to exact wording, and this is exactly the kind of question Ruling Divergence Axes warns against universalizing from one example. What this pairing establishes generally:

• A control-take grant with an explicit stated duration ("until the End Phase") is respected for that full duration once established — it is not treated as something a competing continuous claim can interrupt mid-duration.
• A continuous control-take effect's condition being continuously true does not mean the game re-litigates who currently controls the card at every instant in a way that overrides an active, still-running lingering grant from another card.
• If asked about a different continuous-vs-lingering control-grant pairing, do not assume this verdict transfers automatically — flag that the specific pairing needs its own check, the same way this one did, unless the card texts are functionally identical.

Judge calls to watch for

• Do not assume a continuous control-take effect (an Equip Spell's "while X, take control" or similar) immediately reclaims a monster the instant an opponent's lingering, time-boxed control-take effect resolves. The time-boxed grant holds for its stated duration.
• Do not treat this as resolved by the general continuous-effects mechanic in #17 alone — that file explains when continuous effects apply and stop applying, not how they're prioritized against a competing lingering grant from another card. This file is the specific tiebreaker for that scenario.
• If a player asks about an unrelated continuous-vs-lingering control pairing, do not assume the Widow Anchor/Mikanko Reflection Rondo verdict transfers without checking the specific card texts.
• This is sourced to an official email ruling, not a public Q&A page — be upfront about that sourcing limitation if a player asks for a citation link.
