Ozumat fight Book of Heroes

Tried it 20+ times now, I can’t get past turn 3.

Can someone actually give me clear instructions on this? All I’ve found were people talking theory and no practical advice and I’ve clearly run out of ideas

U just have to beat the right tentacles and pray.
Your mulligan is predetermined, so u should pay attention to that.

There were instructions on the forum, apparently, you haven’t searched well.

I’ve not reviewed this, though, but it answers your question.
