Is Reservoir Walker good in Commander?

Reservoir Walker in Commander — Combos, Decks & Price

Reservoir Walker enters with a +1/+1 counter and gains you 2 life, making every copy or flicker immediately relevant on the board. The five-mana cost is real, but in a shell built around Delina, Wild Mage or any token-doubling engine, each additional copy stacks counters and life at a pace opponents can't ignore.

Reservoir Walker is a Commander card through and through — the life gain and counter accumulation are too incremental for the faster competitive formats, where five mana for a 2/3 with upside doesn't clear the bar in Modern, Legacy, or Vintage. Pauper is its only other realistic home, where the body and life gain can be relevant in a slower, grindier environment. In Commander, Reservoir Walker slots cleanly into any deck that generates multiple enter-the-battlefield triggers — blink, copy, or token strategies all convert its modest on-entry effect into a repeatable engine.
