Gunkan Suship Catch-of-the-Day
The continuous trap that turns every summon into deck advantage
Gunkan Suship Catch-of-the-Day is the card that makes Gunkan Suship feel like a modern engine despite its small card pool. A Continuous Trap that adds one Gunkan card from your deck to your hand whenever you Normal or Special Summon a Gunkan monster, Catch is not a once-per-turn luxury — it fires on every qualifying summon, which is why a single turn with double Shari can produce two searches before you ever overlay. Competitive pilots treat Catch as a three-of staple; budget pilots craft it before almost any Extra Deck ship. This guide explains optimal sequencing, multi-activate math, naming pitfalls that cost ranked games, and when hybrid lists trim copies.
What Catch actually searches
Catch adds any card whose name includes Gunkan — monsters, spells, traps, and Field Spells. That means it can search Gunkan Sushipyard, another copy of Catch, Gunkan Suship Daily Special, or any topping you are missing. The flexibility fixes brick hands where you opened three monsters and zero spells, and it lets you thin dead duplicates when your hand already contains the piece you need.
Search priority changes by role. Going first, pilots often grab Gunkan Suship Shirauo or Gunkan Sushipyard on the first trigger, then grab Daily Special or a second yard on the second trigger. Going second, Gunkan Suship Ikura or Gunkan Suship Uni jumps ahead of Shirauo because OTK damage matters more than long-game negates. Cross-reference topping roles on the main deck guide before locking search habits — autopiloting Shirauo every time leaves lethal on the table.
Set timing and multi-activate value
The most common misplay is summoning Gunkan monsters before Catch is set. If you Normal Summon Gunkan Suship Shari, special summon a second Shari, and only then set Catch, you wasted two triggers that could have added two names. Correct turn-one sequencing: activate Gunkan Sushipyard if available, set Catch, then begin the summon chain.
Multi-activate value scales with how many Gunkan bodies you can produce in one turn. Standard core combo lines generate two summons trivially; Gunkan Suship Shari Red lines can produce three or more when Red special summons itself and pulls a topping from deck. Each summon is another search — this is why Catch outvalues slower once-per-turn searches in pure Suship lists.
Catch also triggers on opponent’s turn if you special summon Gunkan monsters during their turn — rare in pure lists, but relevant in Ryzeal hybrid builds where extenders spill bodies at odd timings. Track how many summons remain legal before setting Catch on turn one; sometimes you set Catch on turn two after an opponent’s board wipe because summoning first would have been interrupted anyway.
Shari Red, reveal, and naming interactions
Gunkan Suship Shari Red complicates Catch timing because Red’s name becomes Shari in hand, deck, grave, and field. When Red special summons off its reveal effect, that summon triggers Catch like any other Gunkan monster — but pilots must verify Red counts as a Gunkan monster for Catch’s trigger condition (it does) and plan searches before committing the reveal.
Reveal lines often want a specific topping from deck via Red’s own effect rather than via Catch search. If Red will summon Gunkan Suship Shirauo from deck negated, Catch’s first search might grab Sushipyard instead of Shirauo because yard activation unlocks non-negated equips. Full Red rules live on the Shari Red card guide; this page focuses on when Catch and Red compete for the same turn’s advantage.
Painful Decision loops also interact: sending Shari to deck and adding Shari does not trigger Catch — no summon occurred. Summoning after Decision still triggers Catch normally. Do not confuse search effects with summon triggers when planning hand size.
When Catch bricks
Catch bricks when you cannot summon Gunkan monsters — Ash Blossom on Shari’s deck special summon, Infinite Impermanence on Red, or floodgates that block special summons leave Catch as a set card with no triggers. Unlike searchable quick plays, Catch does not help when your engine is dead on arrival.
Catch also underperforms when your hand is all spells and traps with zero bodies. Setting Catch turn one with no follow-up summon is correct — it threatens future advantage — but it is not equivalent to having a live search immediately. Normal Summon support from competitive builds like Rescue Rabbit or Unexpected Dai exists partly to guarantee Catch triggers even after disruption.
Heavy back-row metas punish set-and-pass Catch hands. If opponent opens Lightning Storm or Harpie’s Feather Duster, you lose Catch and the turn. Running two to three copies mitigates variance; running zero copies in hybrid lists assumes the other engine carries consistency — a gamble documented on the Ryzeal hybrid build.
Ratios: three versus two versus cut
Pure competitive lists run three Catch. Two copies is acceptable for gem-starved pilots who accept slightly lower multi-search turns. Cutting to one is a hybrid concession when Ryzeal or Primite packages consume spell/trap slots — only do this if the secondary engine searches or special summons often enough to replace Catch’s grind value.
Never cut Catch to zero in pure Suship. The archetype without Catch plays like a Normal Monster deck with extra steps. Festival lists under UR caps may run two Catch instead of three to craft Dreadnoughts first — see Festival Under 5 for priority ordering.
Interaction with other spell/trap support
Catch and Gunkan Sushipyard are partners, not rivals. Yard must be active before equips from hand; Catch searches yard when missing. Gunkan Suship Daily Special equips at quick speed when yard is absent — Catch can search Daily Special to recover from Mystical Space Typhoon on yard.
Broader spell/trap context — Painful Decision, trap ratios, side decking — lives on the spells and traps hub. This page is the Catch-specific deep dive that hub links back to.
Side decking and opponent naming
Side deck rarely removes Catch; instead pilots side extra hand traps and board breakers. Against decks that search heavily, Droll & Lock Bird after your Catch resolves can lock opponent while you already gained advantage — sequencing Bird after your own searches is legal and common in Suship mirrors.
Opponents who know the deck may Called by the Grave Catch after it resolves once — you still keep searched cards, but future triggers require another set copy. Running three copies is partly anti-grave-hate insurance.
Practice drills
In solo mode, test hands with Catch plus one Shari, Catch plus Red plus Shari, and Catch plus no bodies. Time how quickly you can set Catch before second summon. Watch the embedded video above for ranked sequencing under Master Duel’s clock, then compare against written steps on core lines. Catch mastery is repetition — pilots who internalize set-first discipline climb faster than pilots who memorize topping text alone.
Frequently Asked Questions
Quick answers duelist ask most often.
How many copies of Catch-of-the-Day should I run?
Three in pure lists. Two is acceptable on budget or in tight hybrid shells. One or zero only when a secondary engine fully replaces Suship's search loop — rare for pure pilots.
Can Catch-of-the-Day search itself?
Yes. Catch is a Gunkan card, so it can add another copy from deck. Turn-one self-searches are uncommon but useful for setting multiple traps across later turns.
Does Shari Red's summon trigger Catch?
Yes — Red is a Gunkan monster and its special summon triggers Catch if the trap is already set. Plan searches before reveal when Red will also pull from deck.
When should hybrid lists cut Catch?
When Ryzeal or similar engines consume spell/trap space and provide their own searches. Cut to two before cutting Shari or yard — see [Ryzeal hybrid](/builds/ryzeal-hybrid/) for ratios.
Should I set Catch before or after activating Sushipyard?
Either order works before summons begin. Most pilots activate yard first so the first searched topping equips immediately, then set Catch before the first Gunkan summon.
