TrophyCoach has five Clash Royale deck tools, and picking the right one depends on one question: do you already have a deck, or do you want one built for you?
I want a deck built for me — Deck Builder, Build for me (free)
Build for me on the Deck Builder at /tools/deck-builder is the build-me-a-deck tool. Enter your player tag (no sign-in needed; a signed-in player with a linked tag can skip typing it) and it builds decks only from cards you own, at your levels. You choose how many decks (up to 10), a play style (Beatdown, Control, Cycle, Bait, Siege or Bridge Spam), a minimum card level (Skeletons and the Spirits can be exempted), a max average elixir, up to 3 cards every deck must include, up to 8 cards no deck may include, up to 2 of your unlocked Evolutions or Heroes to build around, and rules for one win condition, a building, a spell, or ignoring the meta. Every deck is checked against every rule before it is shown. When fewer decks qualify than you asked for, it lists what ruled out the rest. Each deck loads into the Deck Builder board or opens in the Deck Doctor with one click.
This is the right answer for "make me a deck," "build me a deck with my cards," "build me a deck without Mega Knight," "build a deck around my Evo Knight," and for players who don't know how to build a deck and don't want to fix their current one.
I want the best meta deck I can already play — Deck Finder (free)
The Deck Finder at /tools/deck-finder lists the decks players are running. Enter your player tag (or sign in with a linked tag) and it ranks the current top meta decks by the cards you actually own — each deck gets a composite score = live meta strength (rank, pick rate, published win rate from the tracked-decks pipeline) × your collection completion × a level factor. The level factor compares the deck's card levels with your own median card level — about 1.5× per level above it, the same drop per level below — so a deck you hold at high levels can outrank a stronger meta deck you would field under-levelled. A deck is marked "playable today" only when you own all 8 cards (an Evo slot also needs that Evolution unlocked); a deck missing exactly 1 card is marked "one card short", and decks missing 2 or more are "stretch". You can filter by archetype (cycle, beatdown, control, siege, bait, bridge spam, and more), by win condition, and by Champion.
Filters: the Deck Finder filters by archetype (cycle, beatdown, control, siege, bait, bridge spam, …), by win condition, by max average elixir (≤ 2.8, 3.0, 3.3, 3.6, or 4.0), and by Champion (a specific Champion, or "No Champion"), and can hide decks you can't play yet (any of the 8 cards not owned). Every ranked deck shows its average elixir. There is no elixir sort — decks stay in the ranking order (meta × completion × levels) within the filter.
Asking in chat: the support chat can answer "build me 10 decks under 3 elixir" directly — it lists the highest-ranked tracked decks at your trophy range that fit the cap, each with a Deck Doctor link, and links the Deck Finder with the same cap applied.
Build around my cards: the Deck Finder's Must include box takes up to 3 cards, and the list keeps only decks that have all of them, still in the usual ranking order. Each card it offers shows how many tracked decks at that trophy range have it. With a tag loaded, the player's Evolutions and Heroes appear as one-tap chips. The deck lists don't record which slot runs an Evolution or Hero yet, so an "Evo Knight" pick finds decks with Knight.
Variants: decks that differ by one card are listed once, under the best-ranked of them, with a "+N variants" button that swaps a variant in (for example "Ice Spirit → Electro Spirit"). Each variant keeps its own rank and links.
Trophy ranges: Under 5,000, 5,000–6,000, 6,000–7,000, 7,000–8,000, 8,000–9,000 and 9,000+. Looking up a tag picks the player's range. At 9,000+ the decks come mostly from Ranked battles; Trophy Road above 9,000 uses the same list for now.
The Deck Finder supports a tag link parameter (/tools/deck-finder?tag=%23YOURTAG), so a link that already includes a player tag loads their decks immediately; a maxElixir parameter (/tools/deck-finder?maxElixir=3) that pre-applies the elixir cap; a range parameter (/tools/deck-finder?range=7000-8000; also under-5000 and 9000-plus) that opens a trophy range; and a card parameter (/tools/deck-finder?card=Hog%20Rider,Evo%20Knight, up to 3 cards) that pre-fills Must include.
This is the right answer for "what's the best deck for me," "best deck with my cards," and "which meta decks can I play right now."
I have a deck and want it improved — Deck Doctor (free)
The Deck Doctor at /tools/deck-doctor analyzes a deck you enter: it grades the deck, finds weaknesses (bad elixir curve, no small spell, no anti-air), and suggests specific card swaps. It supports a deck link parameter with comma-separated card names (/tools/deck-doctor?deck=Hog%20Rider,Musketeer,...), so a link can arrive with the deck already filled in.
Hero and Evolution cards: every card in your deck — auto-loaded from your linked account or picked by hand — shows a Hero and/or Evo button underneath it, only where that card has such a form in the game (16 Heroes and 44 Evolutions as of September 2026). The game's slots are one Evolution, one Hero, and one Wild slot that takes either. A Champion takes the Hero slot, or the Wild slot when the Hero slot is full, so a deck holds at most 2 Evolutions, at most 2 Heroes and Champions together, and 3 forms in total. The game never reports which forms you run, so mark them yourself; the analysis and the deck chat then grade the form you picked, not the base card.
Tower Troops: Deck Doctor reads your equipped Tower Troop and every Tower Troop you've unlocked from your linked player tag (Account Settings → Game tags), and recommends one from those you own. There is no manual Tower Troop picker: without a linked tag it can't see your Tower Troop and tells you to keep the one you use now.
Important: the Deck Doctor does not generate a deck from scratch. It needs a deck as input. Someone with no deck should start at the Deck Builder's Build for me, or at the Deck Finder for a ready-made meta deck.
After an analysis, signed-in users can tap "Ask about this deck" to chat with a deck coach grounded in live meta stats. That chat is where specific questions get real answers: "Cannon or Tesla in this deck?", "how do I beat Golem with this?", "what should I upgrade first?"
I want to rate an idea — Deck Builder (free)
The Deck Builder at /tools/deck-builder lets you pick any 8 cards (or paste a deck link) and runs the same instant deck check as the Deck Doctor: win condition, anti-air, spells, a tank killer, average elixir, the 4-card cycle, and Evo and Hero slots, each with the fix it needs. It also shows the closest deck we track at your trophy range. There is no 0–100 score. The Deck Rater at /tools/deck-rater runs the same check on a finished deck. Use either to sanity-check a deck idea before you invest upgrades, then hand the deck to the Deck Doctor for AI swap suggestions.
I need war decks — Clan War Deck Planner (free)
The Clan War Deck Planner at /tools/war-planner builds 4 non-overlapping Clan War decks with automatic card-conflict detection, spell-balance validation, and win-condition checks. This is the answer to "war deck builder" questions.
I want my saved decks or the full workspace — Deck Lab
The Deck Lab at /app/decks has your saved decks and the Pro deck workspace.
- My Decks (free): any signed-in user can save decks, as many as they like, from the Deck Builder or the Deck Lab, and open or delete them in the My Decks tab.
- Pro: the Find a Deck (suggested decks from your collection), Counter This (counters to a specific deck), Upgrade Path and War Day tabs, plus the Royale IQ and Tilt Meter panels. A free user sees what each one does and a link to the Pro plans; the saved decks stay one tab away.
Which deck tool should I use?
Do the deck tools work in other languages?
The tools themselves are in English, but the support assistant and the Deck Doctor chat will answer questions in your language — ask in Spanish, French, Turkish, or any language you're comfortable in.
