I just played a match against a Mono R opponent. I was at 14 life and I duressed them and I saw some burn spells and HSR. Made them discard one of the burn spells and played a spell manually tapping to leave my painland unttaped but with no castable spells in my hand.
Opponent proceeded to burn me until 10 life and then used HSR. Arena didnt give any opportunity to me to use the painland and I immediately lose the game. So if you know your opponent has a HSR and you have a painland you need to have a stop set or a castable spell.
