How to get an instant win on Tombs of Terror boss

[Rhasimir-1573]

Known Bug:

Known Issues List 2019 - Updated Dec 12th

December 5th, 2019 [Mobile] Samsung Note S-Pen does not respond to screen touch. Sathrovarr is currently unavailable to be used in a deck. Murky’s Battle Horn will cause both heroes to be destroyed. You do not receive an invalid deck message when using a deck code that contains a Wild-to-Standard event card. December 12th, 2019 Dwarven Archaelogist does not discount cards from Draconic Lackey. Albatross is not registered as a neutral card.

Did you get to pick new cards after this fight? My bet is no, since both heroes dying results in a Draw, not a Win, and a Draw will not end your run, it will just make you face another boss of the same level.
