Ninja's biggest printed hit is a 12 — one of the smallest ceilings in the game — and the math still favors him against 42 of the 43 heroes he can face. That's not a typo, it's the whole lesson: he never has a big turn, he just never has a bad one. Slash connects on 98% of turns, Delayed Poison keeps scoring while your opponent is the one playing, and every Ninjutsu token you spend makes the board lie about what just hit them.
Your opening turns buy the two things this kit runs on: a poison clock and a token bank. Slash is always live — 98% with disciplined rerolls, 5 to 7 damage by blade count — but the better first move when the dice offer it is Smoke Screen: one blade, two shuriken, one mask, landing on 72% of turns. It deals nothing directly and still swings the game, because it plants a Delayed Poison (3 damage at the end of their turn), hands you a Smoke Bomb, and banks 2 Ninjutsu — offense, defense, and pump from one roll. Poison Blade (a four-in-a-row, 59%) is the aggressive version: 5 damage and the poison together. What you never do early is hunt masks: Shadewalk is a 10% line and the ultimate is 1.3%. Take the guaranteed chip and let the clock math work for you.
The middle game is one rule and one question. The rule: a Delayed Poison should be on your opponent at all times — each token pops once for 3 at the end of their turn and is spent, a 2-stack pops for 6, and nothing in their defensive kit interacts with it. Re-apply through Poison Blade, Smoke Screen, or a Ninjutsu 6 the moment it pops. The question, every time you get hit: is this worth the Smoke Bomb? You hold at most one and it works half the time, so spend it on the spikes — Pyromancer's stacked turns, Treant's Overgrowth, Gunslinger's Deadeye — and eat the chip damage with your face while Shade Shift pays you back about 3.5 per hit. Meanwhile, stay on the gas: the clocks say you out-race almost everyone (8.4 turns against Artificer, 10 against Monk), so every turn spent defending instead of Slashing is a gift to whoever is assembling an engine across the table.
Closing is arithmetic, so do it out loud. A 2-stack of Delayed Poison is 6 guaranteed at the end of their turn, Slash is 5-7 more, and Ninjutsu adds 1-2 per token — count those three sources against their remaining health before you commit to anything. When their defense is the last obstacle, remember the sneaky finisher: Walk the Line (four shuriken, a 54% line) deals the total of two fresh dice, and a total of 6 or less becomes undefendable — the low rolls are the ones nothing can stop. Guard your own endgame honestly, too: your only mitigation is one 50% token, so below 20 health against Barbarian or Monk you are standing inside an 18-damage burst window and hoping. And never plan around dodging an Ultimate — no token stops one, and the only counterplay in the game is altering their dice before it fires, so a held roll-phase card is worth more to you than a full-health Smoke Bomb.
Ninja's die is three blades, two shuriken, one mask, and the reroll math follows the faces. Any opening pair of blades is a keep — Slash is 50% on a single roll and 98% across three attempts, so blades are the permanent safety line. Two early shuriken open Death Blossom (three blades plus two shuriken, 63% of turns): you roll five fresh dice for 1 damage per blade and 2 per shuriken — about 5.8 expected — and if any of the five shows a mask, the whole attack turns undefendable. Smoke Screen at 72% is the easiest set on the board and the best landing spot for a scattered roll. Chase four shuriken for Walk the Line only when three arrive by the first roll — it's a 54% line overall. Straights come to you or they don't: take Poison Blade's four-in-a-row (59%) happily and Shadow Fang's five-in-a-row (25%, for 8 damage plus 2 banked Ninjutsu) when it lands early, but never burn a whole turn chasing either. As for masks — with one face in six, Shadewalk (10%) and Assassinate! (1.3%) are gifts, not gameplans. Take the line when three masks show up on the first roll; otherwise play like those abilities aren't on your board.
Ninja's damage engine runs on tokens, not Combat Points — Ninjutsu does the pumping and poison does the grinding — so your CP is free for the jobs dice can't do. First job: insurance. Against Knockdown heroes like Gunslinger, keep 2 CP banked, because standing up costs exactly 2 CP or your entire Offensive Roll phase, and a skipped turn hurts a never-miss hero more than anyone at the table. In a race you're winning — which is most of them — always pay it. Second job: refuse taxes. When Tactician's Constrict makes rerolls cost extra, take your first roll and move on: Slash is 50% on a single roll, and half a turn beats a taxed one. Same logic against Treant's Barbed Vine, which charges a damage per extra attempt — a fishing Ninja pays that tax two turns out of three, so stop fishing the moment it lands on you. Third job: dice manipulation. With one mask face in six, a card that sets a die is worth more to you than to almost any hero — it lifts Shadewalk from a 10% line to a genuine one-in-three plan, and the ultimate from a 1.3% miracle to a roughly 10% longshot you can at least threaten.
Hold cards in this order. Dice manipulation first — altering dice is the only counterplay to enemy Ultimates in the entire game, and on offense it converts near-miss mask rolls into Shadewalk's undefendable 6 or an on-purpose Assassinate!. Roll-rescue effects second: anything granting extra attempts pushes your 98% Slash and 63% Death Blossom lines toward certainties. A defensive trump third, because your printed defense prevents zero. Sell the rest without sentiment — a card you'll never play was always 1 CP in disguise. On Ninja's own upgrade cards, honesty over guesswork: they aren't in the verified data yet, so no upgrade-path claims here until DiceSlayer verifies them on camera. The one rules anchor worth carrying in: upgrades can never be sold back, and a hero who wins on tempo should be suspicious of any early CP spend that doesn't cash out within two or three turns.
Deny him whole turns, not damage points. Attack negation — Shadow Thief's Shadows, Cursed Pirate's Parlay, Moon Elf's Blind, a well-timed Knockdown — hits Ninja harder than any hero in the game, because his entire pitch is a near-guaranteed 6-plus every single turn. Deny the poison clock where your kit allows it: Monk's Cleanse deletes Delayed Poison before it ever ticks, and even forcing a re-apply costs him tempo. Deny the Smoke Bomb its dream job by feeding it mid-size decisions — every token he spends dodging a 4-damage hit is one that can't blank your real spike. And tax his rolls: reroll punishments like Barbed Vine and Entangle land exactly on the mask-and-straight fishing his flashy lines depend on.
Three windows. The turn right after his Smoke Bomb is spent — the token caps at one, so until a Smoke Screen or a two-mask defense roll rebuilds it, your biggest hit meets zero prevention. Any turn your Ultimate is ready — his one dodge token has no say against it. And the moment you assemble one real burst turn: his ceiling is 12 and his damage barely varies, so a single 15-plus swing puts him behind a clock he cannot spike his way back onto — from there, every trade happens on your schedule.
The engine says Ninja is the last hero worth your ban — favored against 42 of 43 opponents, but never by a landslide, and real answers exist. If your roster leans on slow engines (he farms Alchemist at 67.4, Artificer at 65.5, Paladin at 64.7), banning him is defensible. If you brought Iceman — his only engine-negative matchup at 47.5 — or a genuine coin flip like Barbarian (50.7) or Pyromancer (51.6), keep the ban for something scarier. The community's B-tier read means most opponents won't ban him either, which is exactly why he keeps showing up.
Ninja is the safest pick in a bring-3: no engine matchup below Iceman's 47.5, a core attack that misses fewer than one turn in fifty, and per-turn damage that varies by barely a point — you can slot him blind into an unscouted field and know roughly what you'll get. Build around his real gaps: pair him with a burst threat that punishes the token-economy heroes (Gunslinger, Huntress) whose engines the math undercounts, and bring something that handles Iceman. The community pegs him B-tier with an undefeated small-tournament sample in the notes — read that as low ban-priority attached to a high floor, which is a quiet roster cheat code.
Ninja is the anti-clock hero: his modeled kill clocks sit at 9 to 13 turns against most of the field — the slow spots are the same heroes who already trouble him, Barbarian at 16.2 and Iceman at 27.6 — so in 3/1/0 Swiss he usually converts full wins inside the round timer instead of settling for 1-point draws. The pace risk runs the other way — stall heroes like Shadow Thief cycling Shadows want to stretch your 9-turn plan into 15 rolls. Don't take the bait: jab with base Slash into negation turns and never feed a negate your best roll, let poison keep scoring through the stall, and remember a fast 3 in round one beats a perfect game that finishes after time.
