Dealt is the past-tense and past-participle form of the verb deal. Dealed appears occasionally, especially in the phrase wheeled and dealed (mainly for the rhyme), but it’s not a dictionary-approved form. It might someday enter the language, but so far it has not caught on the way similar words such as learned, smelled, and spelled have.
