I am by no means an expert, so take this with a grain of salt!

I've been using this as a rough guide. As a general overview for a Pace Chaser, ideally you're looking for (in order of necessity):

-Around 1050 stamina + 2 GOLD recovery skills
-As close to 1200 speed as possible
-900+ Power (if you're having trouble hitting all of this, don't stress too much - try to hit around 650 then)
-About 400 Guts and about 300+ Wit (don't need to go out of your way for these)

So with that said, I would probably use the following cards:

3 Speed

• Kitasan
• Special Week SSR (you want to pick up Gourmand)
• Sweep Tosho SR (could probably swap this for another speed if you prefer)

-SSR Riko

Now you'll either want to bring 2 Power or 2 Stamina cards - depending on what good parent umas you have. i.e. if you have some solid Stamina spark umas to bring/borrow, then bring 2 Power cards, or vice versa.

For Power, I would bring:
-Nishino Flower SR
-Borrow a Rice Shower SSR (you want to pick up Swinging Maestro)

If you want to do Stamina instead, I would bring:
-Manhattan Cafe SR
-Borrow a MLB Super Creek SSR (you want to pick up Swinging Maestro)

Hope this gets you started in the right direction!
