The Commander
The Watcher in the Water enters tapped with nine stun counters on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)
Whenever you draw a card during an opponent's turn, create a 1/1 blue Tentacle creature token.
Whenever a Tentacle you control dies, untap up to one target Kraken and put a stun counter on up to one target nonland permanent.
Guide
Gameplan
The Watcher enters tapped under nine stun counters, so it's a passive engine rather than an early beater—you load up on instant-speed and opponent-turn card draw to flood the board with 1/1 Tentacles. Sacrificing or trading Tentacles untaps the Watcher (shedding stun counters) while stunning down opponents' key permanents, locking them out turn after turn. You grind value with draw, control the board with repeated stun-tapping, then close with a swarm of tokens or a finisher.
Strengths
- Generates a steady stream of free tokens just by drawing on opponents' turns
- Built-in soft removal/lockdown by stacking stun counters on threats and lands each turn
- Mono-blue gives access to the best counterspells, card draw, and protection
- Token swarm enables sacrifice synergies, blink, and go-wide payoffs
Weaknesses
- Enters tapped with nine stun counters, so it does nothing the turn it lands and is slow to free up
- Token generation only triggers on opponents' turns, requiring instant-speed draw to be reliable
- Mono-blue lacks efficient creature removal and life gain
- Heavily reliant on the commander; if it's repeatedly removed the engine stalls
- Tentacles are tiny and fragile to board wipes
Key Cards
- Teferi's Ageless Insight — Doubles opponent-turn draws into multiple Tentacles per trigger, supercharging the token engine.
- Consecrated Sphinx — Draws two cards on each opponent's turn for explosive Tentacle production.
- Mystic Remora — Cheap repeatable opponent-turn card draw that mints Tentacles while taxing the table.
- Rhystic Study — Reliable opponent-turn draws that translate directly into tokens and value.
- Ashnod's Altar — Free sac outlet to kill Tentacles on demand, triggering untaps and stun counters at will.
- Skullclamp — Turns dying 1/1 Tentacles into two cards each, fueling draw and the death trigger loop.
- Quicksilver Amulet — Cheats the Watcher in untapped, bypassing the nine stun counters entirely.
Upgrade Path
Add more instant-speed and opponent-turn draw doublers (Teferi's Ageless Insight, Alrund's Epiphany loops) plus free sacrifice outlets like Ashnod's Altar and Phyrexian Altar to weaponize the death trigger. Include ways to cheat the Watcher into play untapped or remove its stun counters faster, and stronger interaction (Cyclonic Rift, Force of Will) to protect the engine. To push to cEDH, lean into a tight stun-lock combined with card-advantage engines and a compact win like Thassa's Oracle backed by tutors.

Archetypes
- Spellslinger Control — Instant-speed draw and counterspells on opponents' turns fuel both Tentacle creation and the stun-lock.
- Tokens / Go-Wide — Free Tentacles snowball into a wide board that anthems and overrun effects can convert to damage.
- Aristocrats — Sac outlets repeatedly kill Tentacles to trigger untaps and stun nonland permanents for control.
- Stax / Pillowfort — Stacking stun counters on lands and permanents each turn taxes and locks down the table.
