Turtle Team-Up — MTG's TMNT co-op format, rules, and boss phases

For the first time, Magic has a full cooperative boxed experience: Turtle Team-Up. Two to four players pick prebuilt Turtle hero decks, share a Momentum tracker, and face a scripted boss deck starring Shredder and his plans. No deckbuilding required — open the box, pick your turtle, and beat the baddies together. Here's how it works and what to expect.

What's in the box

Turtle Team-Up retails around $49.99. You get four 60-card hero decks (one per Turtle), a 30-card enemy/boss deck, and four Play Boosters to add more cards to your pool. Players choose a hero deck, crack their booster for extra options, then take on the boss as a team. The boss deck is a scripted stack: each turn it flips a card and executes an effect — spawning Foot Soldiers, dealing damage, or advancing the scenario. Your job is to survive the assault and take the boss down before the script runs out or your life total hits zero.

Team Momentum

Players share a Momentum counter starting at 0. It goes up by 1 whenever a Turtle deals combat damage to the boss or defeats a Foot Soldier token. You can spend 5 Momentum to discard a boss card after reading it — a way to skip the worst effects if you've been building up. That makes combat decisions matter: do you clear tokens for Momentum or go straight at the boss?

Boss phases

The encounter is divided into three phases. Mutation counters on the boss track progress; at certain thresholds the boss advances and gets nastier.

• Phase 1 — Foot Clan Assault: The boss creates two 1/1 Foot Soldier tokens with menace each turn. At three Mutation counters, the boss advances to Phase 2.
• Phase 2 — Shredder Strikes: The boss gains double strike and +2/+2. When the boss deals damage, each player must sacrifice a creature or pay {2}. At six Mutation counters, Phase 3 begins.
• Phase 3 — Super Shredder Showdown: Players lose 2 life for each noncreature spell they cast. When the boss attacks, it becomes a 10/10 indestructible until end of turn. This is the final push — the same Super Shredder that's a mythic in the main set appears here as the climactic threat.

Difficulty modes

Three difficulty settings change life totals and optional rules. Casual Pizza Party gives 30 life and lets you skip Phase 3 for a shorter game. City Streets Challenge uses 40 life and the full three-phase script. Nightmare Mode uses 50 life, stronger Foot Soldiers, and Scheme cards for a harder run. Pick the level that fits your table.

Is it worth it?

Turtle Team-Up is aimed at kitchen-table groups and TMNT fans who want to play Magic with friends without building decks or playing head-to-head. The product is self-contained: you don't need other TMNT product to play. If you want a co-op Magic experience and like the theme, the box delivers. If you're mainly after singles for Commander or Standard, the Play Boosters inside are the same as in the main set; the unique value is the format and the prebuilt hero vs. boss experience. The chart below tracks Super Shredder from the main set — the same character that caps off the co-op boss fight.
