The way I see to make Ezra playable is to force or encourage your opponent into claiming early or turn their dice to blanks so they can’t resolve them. The best way to do this is with a battlefield like Arena of Death or Mean Streets. Force Jump and Force Focus are perfect for turning your opponents dice to blanks and can be played on Ezra with his first ability.

If they do claim early with dice in their pool, there are a few cards that can really help you take advantage. Inflame and Shootout are two that quickly come to mind. Inflame lets you turn one of your opponents dice to a side showing damage, which will let you resolve it with Ezra’s ability. Inflame has additional play besides turning their dice to damage so you can use them. You can turn dice to a matching damage side for Easy Pickings or any damage side for use with Into the Garbage Chute.
