if I control mesa enchantress and phyrexian tyranny and Psychosis Crawler
I am at 2 life and other player has 1 life
I cast Dark Flavor getting me to 1 life and now I draw a card from the enchantress but I dont have the 2 to pay for my phyrexian tyranny so I lose 2 life but opponent also is supposed to lose 1 life from the crawler is it a draw?
