I'm pulling out of the parking lot. We all know what that means. Well, do we? It's time for drive from work.

So, again, I have a podcast. Tomorrow I'm going on vacation. And so this is my last chance to get a podcast I've been working on on backward compatibility.

So I thought I would try one last chance of it.

I think I can do a slightly better version.

Okay, so what is backward compatibility?

Let's start there.

So, magic has lots of cards, because we've been making this game for 31 years.

So backward compatibility talks about making, when you make something, how much does it interact with stuff we've already made before?

So I'm going to be, in order to get into this topic, I needed to go through some vocabulary and talk through some concepts.

And then I will leap into the core of backward compatibility.

Okay. So first I need to explain explain there's a spectrum of, from the magic cards to be made.

On one end is what we call modular, and the other end is what we call linear.

So the idea of a modular card is it's, you can take one, a modular card and put it anywhere it's a card that just

works in a vacuum the more modular the more it works in a vacuum a classic examples might be a kicker

or um flashback or cycling like if there's just a good card with one of those abilities, you can just put it in your

deck and you can play it. You don't need any other cards. The other end of the spectrum is linear.

Linear means it begets you do something. A classic example that would be Goblin King. Goblin King says,

all your goblins get plus one plus one. Well, that is telling you play a lot of goblins this

card is better the more gobbins you play so the idea on the spectrum is how much is this card

telling you what to play with it the more linear it is the more it tells you the more modular it is

the less it tells you um now there's another thing that we, what we call parasitic.

What parasitic means is that the things you need for this card, and usually it's when you're talking about a linear car, because linear cards need things, only shows up in the set that it appears in.
