Just now on Arena I was playing against a [[Sauron, the Dark Lord]] Historic Brawl deck. I realized that I had lethal, but played the last 1-mana creature in my hand before attacking.
I then realized that I'd just played [[Delighted Halfling]].
Before beating Sauron.
In the Phantom Sealed event for LOTR I opened [[Frodo, Sauron's Bane]] and [[Gollum, Patient Plotter]]. Late in the game I had both of these out and my opponent just played a 2/4 at a healthy 15 life. Frodo was upgraded once and I was tempted 3 times at this point.
On my turn I cast [[Lash of the Balrog]] for B targeting their creature, sacrificing Gollum and triggering the 4th ring temptation. With BBB remaining I leveled up Frodo and swing unblocked for the win!
Gollum was tempted by the ring at the end and ultimately "sacrificed," and Frodo is alone for the win!
