Even if you can't make Adeline work on its own as a commander, you can always add it to the Winota, Joiner of Forces deck and watch it obliterate the battlefield.
The last ability is especially useful in multiplayer matches. The more opponents you have, the bigger number of tokens you can produce. If it's 4-player commander, then you get three tokens and the power of Adeline equals four.
If your creatures survive, then each turn her damage power just keeps growing!
