Here is a little something to ponder: how much damage could you do in a single game? Well, I spent about 65 hours to find out.
If you’re not familiar with Forge, I definitely recommend to check it out. It is a Free/Open Source M:TG engine that has a (not entirely dumb) AI, network play, and just about every single card you could imagine. With this engine, I constructed a non-legal deck with a card combo with an infinite loop and exponential growth both in damage and creatures. And then I played games until I could execute the combo and see just how much damage I could do.
Unfortunately, the software isn’t really built for these kinds of Johnny tactics, and it got incredibly slow. So slow in fact, that by the end, when the stack had 512 Scute Swarm
triggers, it took days for it to resolve (and give the AI a chance to respond to each and every one).
Anyhow, here are some screenshots I took, and the deck. I tried to include the game log, but I think I am bumping up against a body length limit on posting.

For non-infinite I’ve done a couple million with coats of arms, kjeldoran outpost, and a couple mogg infestations, but that was years ago in a two headed giant game so only technically countd.
