In a draft match, I controlled both Eladamri, Korvecdal and another creature. I casted Uro, Titan of Nature's Wrath from my hand. Its two abilities triggered upon entering the battlefield. I chose to resolve its draw a card and play a land ability first, putting a Forest onto the battlefield. At this point, I had the ability to pay for all costs of Eladamri's activated ability. However, I couldn't activate it in response to Uro's abilities, and the system automatically skipped this opportunity. This resulted in Uro being sacrificed and going to the graveyard, preventing me from putting the large creature from my hand onto the battlefield, and thus, I lost the game.
