What it does
Forestwalk makes a creature unblockable as long as the defending player controls a land with the Forest type. It's an evasion ability tied to your opponent's mana base—if they're playing green (or any deck with Forests), your Forestwalker gets through untouched.
The key nuance: it checks the land type, not the name. Any land with the Forest subtype—like dual lands (Breeding Pool, Temple Garden) or anything turned into a Forest—triggers it, not just basics named "Forest." Conversely, a player who's "green" but runs only nonbasic, non-Forest-typed lands gives you nothing. Forestwalk also only grants unblockability; it doesn't stop removal, abilities, or "can't be blocked" workarounds the defender might have.
In Commander's multiplayer format, landwalk is unreliable since it depends on each specific opponent's lands. It shines against heavy green tables but can be dead weight elsewhere—consider it a situational, low-cost evasion rather than a guarantee.
