Thank you so much for your kind words! And thank you for bringing this to my attention! It was meant to say 'Deep Strike Tokens' instead of 'Ambush Tokens' in Step 6. It's a clerical error as the Battlemaul 4K rules were written on top of the Modern variant rulebook layout.
The issue has been fixed and you can download the updated file now. If you perchance locate any other such mistakes, please do let me know!
