43% of games where Regisaur Alpha resolved ended in a win for the caster, a +21.2 percentage-point lift over the 22% baseline when it stayed in the library.

Regisaur Alpha is a niche but impactful staple of Dinosaur tribal Commander decks. Across 501 tracked multiplayer games on Playgroup Live, it appears in 221 of 5023 distinct decks, and the win-rate signal is one of the clearest we see for a tribal-specific card at this mana value.

When Regisaur Alpha reaches the battlefield, it delivers immediate board presence: a 7/7 split across two bodies, haste granted to every other Dinosaur you control, and a 3/3 trample token entering alongside it. The cast win rate of 43% against a library baseline of 22% is a +21.2 pp lift across 109 cast observations and 311 library observations. Both sample sizes exceed 15, so this is a directional result worth tracking. Of drawn copies, 75% were cast before the game ended, and median first cast lands on turn 7.

The card fits almost exclusively into Naya (G/R/W) Dinosaur shells. Pantlaza, Sun-Favored and Gishath, Sun's Avatar lead the commander distribution by a wide margin, which reflects how tightly Regisaur Alpha's haste anthem synergizes with mass-Dinosaur combat strategies. Outside of Dinosaur tribal, 4% overall inclusion confirms it is a dedicated-archetype card rather than a broad staple.

≥ +11.9pp

Players who cast this card win 43% of the time (n=109) , vs 22% when it never left the library (n=311).

When players drew this card but left it in hand, they won 24% (n=39) — about the same as leaving it in the library. Those players survived long enough to draw it, so the gap above is about the card resolving, not just about surviving.

Observed gap +21.2pp; 95% confidence interval +11.9pp to +30.5pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Frequently Asked

How often is Regisaur Alpha drawn and cast in a typical Commander game?

In 501 tracked multiplayer games where Regisaur Alpha was in a deck, it was drawn 31% of the time. That is consistent with a singleton in a 100-card deck that costs 5 mana and is not a universal staple. Of those 158 drawn copies, 75% were cast before the game ended. Median first cast is turn 7, with the distribution running from as early as turn 2 up to turn 15 in longer games.

What is the win-rate impact of casting Regisaur Alpha?

Games where Regisaur Alpha was cast show a win rate of 43% across 109 observations, compared to 22% across 311 participations where it stayed in the library. The +21.2 pp delta is a consistent early signal across a sample large enough to be directional. It reflects the card's immediate board impact: two bodies, haste for the tribe, and a trample token all at once.

What turn does Regisaur Alpha typically hit the battlefield?

Median first-cast turn is 7, with the interquartile range running from turn 6 to turn 9. The mode is turn 7. A small cluster of early casts before turn 5 likely reflects ramp-heavy Dinosaur openings. Of drawn-and-cast instances, 31% were cast on the same turn they were drawn, meaning most players hold it a turn or two while they develop mana.

Which commanders run Regisaur Alpha most often?

Pantlaza, Sun-Favored dominates the list with the highest raw deck count among tracked games, followed by Gishath, Sun's Avatar and Atla Palani, Nest Tender. All three are Naya (G/R/W) Dinosaur tribal commanders. Owen Grady, Raptor Trainer represents the primary two-color (G/R) option. The concentration is tight: Regisaur Alpha is almost exclusively a Dinosaur-tribal card and the data reflects that clearly.

Is Regisaur Alpha legal in Commander and other formats?

Regisaur Alpha is legal in Commander, as well as Legacy, Modern, Pioneer, Vintage, Historic, Timeless, Duel Commander, Brawl, Gladiator, and Oathbreaker. It is not legal in Standard, Pauper, Pauper Commander, or Premodern. In Commander it is unrestricted, and in Duel Commander it is also legal with no restrictions.

How spread is the Regisaur Alpha data across players?

202 distinct players have brought Regisaur Alpha to a tracked game on Playgroup Live. No single player accounts for an outsized share of the dataset, which is a positive sign for data reliability. The spread across primarily Dinosaur-tribal pilots also means the behavioral patterns, cast turn, draw-to-play rate, and win rate, are reasonably representative of how the card actually plays in its intended archetype.
