Chrome Host Seedshark
Creature — Phyrexian Shark
Flying
Whenever you cast a noncreature spell, incubate X, where X is that spell's mana value. (Create an Incubator token with X +1/+1 counters on it and "
: Transform this token." It transforms into a 0/0 Phyrexian artifact creature.)

Chrome Host Seedshark turns every noncreature spell you cast into a free Phyrexian mite token with toxic 1, and in a format full of instants, sorceries, and artifacts, that snowballs fast. The three-mana body is unassuming, but decks built around Tetzin, Gnome Champion and similar artifact-spell engines treat it as a mandatory inclusion.
Best Commanders
Commanders with the highest synergy
Tetzin, Gnome Champion
Tetzin, Gnome Champion decks cast a relentless stream of artifact spells to trigger their commander, and Chrome Host Seedshark converts every one of those casts into a free mite token — the two engines run on identical fuel.
Galazeth Prismari
Galazeth Prismari wants artifacts on the battlefield to tap for mana, and Chrome Host Seedshark manufactures a new one every time you fire off an instant or sorcery, turning spell-heavy turns into a board-wide mana battery.
Gimbal, Gremlin Prodigy
Gimbal, Gremlin Prodigy cares specifically about artifact tokens entering the battlefield, so Chrome Host Seedshark's mite output directly upgrades Gimbal's own trigger and keeps the token count climbing every spell.
Jin-Gitaxias
Jin-Gitaxias decks cast an above-average density of noncreature spells, and Chrome Host Seedshark is a steady token printer that scales with that spell volume — the toxic 1 riders are a bonus on top of the raw board presence.
Brudiclad, Telchor Engineer
Brudiclad, Telchor Engineer needs a critical mass of tokens before its combat step payoff kicks in, and Chrome Host Seedshark passively fills that quota across the game without dedicating extra card slots to token producers.

Commander is Chrome Host Seedshark's native habitat — 100-card decks full of noncreature spells give it more triggers than any 60-card format can reliably provide, and the mite tokens compound quickly when an entire table's worth of turns passes. In Modern and Pioneer, it has seen fringe play in artifact-combo and proliferate shells, but three mana for a 3/4 that requires spell density to pay off is a tough sell in formats where tempo is everything. Legacy and Vintage have the spell volume but rarely need a creature that slowly drips out 1/1 tokens when more direct win conditions are available. Oathbreaker offers a middle ground — a planeswalker-focused format with higher noncreature spell counts than most Commander pods — but Chrome Host Seedshark's real home is still the hundred-card format where the engine has room to breathe.
