Favorite Interactions/Combo

I realized that one of the most satisfying thing in a card game is finding that one combo that wins the game or turns the table. Your deck lines up, your mana is full, your eyes are wide. You lay down that specific set of cards you thought about when you set the deck together and it just feels like you're the protag of a book you wrote. Self indulgent and nobody likes it but you. So...

What're your favorites? Personally my recent discovery of Fiora and Judgement for instant win has been tickling my giddy gland. 

They Who Got Fat -> They Who Endure + Atrocity

I guess my opponent is in for some trouble...
Even if he has The Ruination, the next one will be at least a 19/19 while the third a guaranteed 20/20+ setting up an OTK play on Turn 9.

My deck can be very disgusting sometimes :X

Well, my favorite "interaction" is hands-down Draven's response to Teemo: https://twitter.com/disguisedtoast/status/1195773969279803393?lang=en

But as far as combos go, I've been playing a lot of Maokai level up -> nexus damage -> 2x Pilfered Goods = you're dead at the start of your next turn.

Using SI, play Neverglade Collector, and in following rounds play combinations like Kalista followed by Haunted Relic; and Overgrown Snapvine followed by Brood Awakening and Haunted Relic. You do so much chip damag
