If you can manage to keep Ezuri out for very long, you should be able to rack up enough experience counters to pump up some key creatures, though I would understand anyone being reluctant to running an experience counter commander in the 99 of a deck
In Commander, however, where fast mana is absolutely everywhere, this card can be played surprisingly early
Even if you're not playing a Kindred theme that will just take Radagast out of consideration entirely, you will eventually hit a happenstance of creatures in play that will have you putting creature cards on the bottom, not to mention the likelihood that you'll pull all non-creatures
Based on the latest market prices tracked on TCG Stacked, Pikachu ex is worth about $40.89 USD
This allows you to free up your disruption and removal and then consequently your mana to do other things
