Siona, Captain of the Pyleas card art
Siona, Captain of the Pyleas generates a 1/1 Human Soldier token every time an Aura enters the battlefield attached to a creature you control — pair her with Shielded by Faith and you have an infinite token loop on the spot. Gylwain, Casting Director accelerates that engine by stapling Role tokens onto creatures automatically, turning every cast into a trigger.

Commanders with the highest synergy

01
Gylwain, Casting Director

Gylwain, Casting Director

59.7% of decks · synergy 0.56

Gylwain, Casting Director runs Siona, Captain of the Pyleas in nearly 60% of builds because every Role token Gylwain generates is an Aura entering attached to a creature — each one triggers Siona and floods the board with Human Soldiers before opponents can respond.

02
Ellivere of the Wild Court

Ellivere of the Wild Court

45.7% of decks · synergy 0.42

Ellivere of the Wild Court is a Virtuous Role factory, and Siona, Captain of the Pyleas converts every one of those Roles into a creature — Ellivere decks include Siona in over 45% of lists precisely because the token generation is essentially free.

03
Mazzy, Truesword Paladin

Mazzy, Truesword Paladin

33.1% of decks · synergy 0.33

Mazzy, Truesword Paladin bounces Auras from the graveyard back to creatures, and each return trigger fires Siona, Captain of the Pyleas again — the two together turn removal into a token production engine rather than a setback.

04
Yenna, Redtooth Regent

Yenna, Redtooth Regent

20.7% of decks · synergy 0.17

Yenna, Redtooth Regent copies Auras at the beginning of combat, and every copy that enters attached to a creature gives Siona, Captain of the Pyleas another trigger, compounding the token count without any extra mana investment.

05
Uril, the Miststalker

Uril, the Miststalker

14.3% of decks · synergy 0.14

Uril, the Miststalker decks stack Auras aggressively to grow a single threat, and Siona, Captain of the Pyleas turns that stacking into a board of tokens — useful insurance if Uril gets answered, and a backup win condition if combat damage stalls.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Commander is where Siona, Captain of the Pyleas lives — she headlined her own infinite combo deck for years and slots just as cleanly into the 99 of any Aura-heavy Selesnya build. In Legacy, Modern, and Pioneer she's technically legal but sees no competitive play; three mana for a 2/2 that tutors a single Aura to the top of your library is too slow and too narrow for those formats. Vintage is the same story — legal on paper, irrelevant in practice. Oathbreaker gives her a second home as a signature-spell-style commander in a dedicated Aura shell, though the format's smaller pool limits how reliably you assemble the combo.

Price Context

Current price

$0.18 bulk tier

At $0.18, Siona, Captain of the Pyleas is deep bulk — a two-piece infinite combo piece at a price that makes it essentially free to include. Bulk rares with established combo pedigree don't typically spike unless a new enabler pushes them into the spotlight, so picking up copies now costs less than a sleeve protector.
