As much as I dislike the sorrels growing in the back garden, their roots break it up.
So perhaps a sorrel seed party this year and then kill it off makes digging easier?
Some plants do perfectly well in wet and poor clay. If you want a garden magazine garden that won't be possible though... vetch, buttercups, alder, dandelions don't score high ;)
Some weeds / vegetables can break up clay.
