I also love this with a double strike enabler like Fireshrieker or Gruul's Dragon Attack Trigger Atarka, World Render that also has flying and trample
You can fetch out the perfect Rebel for the given situation - such as the flying, protection from Black Nightwind Glider
Mister Fantastic alone can set up so many infinite combos, making him worth the price of admission
Transcendence Combine lifegain and Transcendence with cards listed above that make you unable to lose, and your game ends in a draw of a never ending trigger if no one can break it up
But until some good +1/+1 counter effects mixed with enchantment synergy cards are printed, this one kind of bites the dust
Unfortunately, that's a very specific use case that doesn't just need a deck built around it, it also needs a special situation within said deck
