Then MTG would be a D&D spinoff. I'm not really sure how I feel about that, but we would have gotten trap cards a lot sooner.

What if speculative fiction (fantasy and scifi) were rightfully held as the highest form of literature?

Oh my god, "Classical Literature" would be interesting ! A dream !

What if MTG had a normal damage system used by every other game ? Damage wears off ugh ugh ugh .

It would open up mechanical space for a regeneration mechanic that makes sense.

What if wasps made honey?

I mean, if wasps naturally secreted honey like bees, absolutely nothing.
However, if wasps could MAKE (i.e. produce) honey, that would imply that they are perfectly sentient, and, moreover, externally adept at biotechnology, as producing honey is a challenging task even while using the most advanced modern biochemical methods.
Greek philosophers would certainly reconsider their worldviews... "Human is a measure of all things" ? Nah.
Given that both humans and wasps are, objectively speaking, pr...ks, there would probably be a lot of human - wasp wars.
History wouldn't be remotely same.

What if Donald Trump was one of founders of USA ?

I suspect the US would be on their 5th republic by now. Most countries fail the first time around and since Trump's having trouble running an established country...

What if our current level of technology is actually the result of time travelers bringing back goodies from the future?

What if all geniuses of history are secretly saved from death by time travelers and are settled into a future museum/lab ?

Then the time travellers will have at their disposal the greatest weapon of mankind.

What if dogs and cats were actually just subspecies of the same animal?

https://en.m.wikipedia.org/wiki/CatDog
Something like that ?

What if about 15% of all conspiracy theories are true ?

Then the all-seeing global shadow government is spending too much time keeping secrets and not enough time running things. Have you seen the world lately?

What if the world was run by vampires?

I sure hope they'll turn us all after we will design a properly cheap way of producing artificial blood.

What if chocolate isn't chocolate ?

Then we have achieved a paradox of semantics.

What if the play by post forum actually had active members?

Then there would be no need for such a question.

What if beer was classy and wine was crass?

Then vodka would be a to-go drink for gifting it to important people, and congac - a fuel for alcoholism.

What if MTG did official crossover sets?

Then it would probably turn out that Twilight Sparkle is a Planeswalker.

What if people stopped arguing about the holidays and just tried to follow the spirit of whichever holiday they are celebrating instead?

The holiday season would be an insane time due to EVERYONE following the spirit of holidays. That would backfire horribly.

What if humanity could literally do anything if 99,9% of humans would agree on what to do?

We might already be living in that world. We'll never know, because it will never happen.

What if people could actually agree things?

Earth would be way happier and way more boring.

What if there was no emotion of boredom?

Then it would be a lot easier to get things done.

What if half the world's population were secretly robots and didn't know it?

Then man, are they going to be surprised when they get to Robot Hell.

What if cars could hail each other like spaceships in Star Trek?

Then maybe, no, surely, I would make a real positive difference in how the people around me drive.

What if our pets were really in charge all along?
