Did a Core Set 2020 draft on Arena.
Pack 1, pick 1 was Loxodon Lifechanter. Since it was pack 1, pick 1 I could grab all the absolute garbo life gain cards over 3 packs.
Pack 1, pick 2 was a Bag of Holding.
During a grindy game I put 2 copies of Dawning Angel under my Bag of Holding.
I eventually pop the bag and cast both copies to just stay in the game after surviving a combat step where my opponent cast Overcome and a Might of the Masses.
I'm down to 6 life or so when I finally drop the Loxodon Lifechanter. My life total goes back up to 16 with the comes into play trigger on the card.
I double block a 5/x flyer with the 2 Dawning Angels the next turn. Still at 16 life.
My opponent has a nice board that includes 1 copy of Ferocious Pup. I attack into my opponent with the Loxodon Lifechanter.
My opponent thinks something is up but black and white can't really trample so they chump with the Ferocious Pup (what a monster) and I use Loxodon Lifechanter's activated ability once to make it a 20/22.
Then I cast Moment of Heroism on the Loxodon Lifechanter.

22/24 lifelinking attacker puts me up to 38.
I eventually grind my opponent out just swinging in with the Loxodon Lifechanter alone over the next few turns.

Core Set Magic making life gain Timmy af.
