Garruk, Curse Breaker

Unlike Elspeth, Storm Slayer, Garruk immediately makes a 4/4 and draws a card; Mono-Green can also repeatedly trigger his draw engine.

Could be wrong if Five mana may be too slow against the current aggressive and spell-focused Standard field, limiting him to a small number of copies.

The 4/4-plus-card floor is credible midrange value, but Garruk is less immediately controlling than Teferi, Hero of Dominaria and expensive for Pioneer.

Could be wrong if Efficient removal and fast linear decks may make a five-mana walker without immediate disruption untenable.

Amulet Titan can supply power-4 triggers, but Garruk is far slower and less uniquely impactful than Karn, the Great Creator in Modern big-mana shells.

Could be wrong if A dedicated large-creature shell could exploit the untap and draw abilities better than expected, but no such support is established here.

A five-mana green walker is a major rate liability in Legacy; even his self-contained 4/4-and-card mode is slow versus the format's efficient engines.

Could be wrong if Fast mana or a niche green prison shell could make him castable earlier, though the supplied context does not establish one.

In creature-heavy green decks, Garruk replaces himself through his own Beast and can turn repeated power-4 entries into substantial card flow.

Could be wrong if At five mana, he is vulnerable before generating repeated draws and competes with more resilient green draw engines.

His -3 immediately produces a trampling 4/4 and a card, while later large-creature entries snowball advantage; he is an excellent first pick.

Could be wrong if Unknown speed and removal density matter: a board that can quickly attack a low-loyalty Garruk reduces his repeat-value ceiling.
