I'm pulling on my driveway. We all know what that means. It's time for their drive to work.

Okay, so today's drive is going to be about AB mechanics. I will start by explaining what AAP mechanics are.

Then I will talk about how we design for them and the challenges of A-B mechanics.

Okay, so let me start by defining what is an A-B mechanic.

In order to be an A-B mechanic, you need to have two things.

First off, A is usually the mechanic or the thing that's self-referential.

A is, I care about something.

And in order to play, I need this thing.

A needs something.

B is the thing that A needs.

Usually B is something that exists.

That isn't...

Usually B isn't relying on A. The one probably

counter example to that is meld, where I, the left side and the right side, and the left

side needs the right side, and the right side needs the left side. But that's a little

normal. Normally in an A-B mechanic, let me give you some

examples of A-B mechanics. Madness. So madness is a mechanic that says, if I am discarded,

you may pay this usually cheaper cost to play me. Well, madness spells require discard. If there's no discard, madness doesn't mean anything. So the A here is

madness and the B is discard. Splice into arcane. The idea is these cards, you can spend the

splice mechanic to put the effect onto an arcane spell that is on the stack.

So in order to use splice into arcane, you need arcane spells.

So A is splice, B is arcane, arcane spells.
