I can see this as a somewhat decent filler kraken in a Dimir kraken EDH deck, but there isnt much to be excited about here other than that
Each of the Commander decks is built around a specific game, with four of the most popular ones being chosen (VI, VII, X, and XIV)
Olivia seems strong with all the cards that increase noncombat damage, like Solphim, Mayhem Dominus and Ojer Axonil, Deepest Might, though that may distract from the theft plan
The mana value is a bit restrictive, requiring two white mana and one blue, but it shouldnt be too difficult to hit that in Commander
To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions
Glarb is one of the Bloomburrow commanders thatll see play in the command zone, but I think this noble frog also has a chance in Standard if theres a shell it can go in
