Dunk Lords

Ok so first let's get this out of the way....YES this achievement can be a pain in the butt even on game 4 since the CPU has incredible items then you do but with patience and not throwing your controller across the room this can be done. So each player has different stats and abilities to help you over come your opponent. So it really depends on what play style you like. If you like playing brute type than having more stamina then i wish you good luck.

The players that worked for me the best (and i hope they do for you as well) was picking Gwen (The Cat) and Frank (The Strawberry). Both have the best stats in my opinion than everyone else.
Gwen:
Strength: Lvl 5
Toughness: Lvl 1
Stamina: Max Lvl
Quickness: Lvl 5
-------------------
Dunk: Grade A
Jumpers: Grade A
Threes: Grade B
------------------
Special:
Ankle Breaker
Charged: Giant Yarn
------------------
Frank:
Strength: Lvl 1
Toughness: Lvl 1
Stamina: Max Lvl
Quickness: Max Lvl
-------------
Dunk: Grade D
Jumpers: Grade A
Threes: Grade A
------------------
Special: Jelly Jar Jail
Charged: Berry Bomb Strike.
----------------
With this two i feel like they balance each other out. Each Item has it own perks which help to some degree and each match you win you get to lock one so you can use or trade it for something better during your next game match. It would be helpful to list all of them but unfortunately I'm just going to show you which ones worked for me and how they work.



So if you have ever get the chance to get the Fusion core, Shock Gauntlets, or the Ninja Kicks during your first or Second match, buy them immediately!

Shock Gauntlets: (Will shock the player when they steal the ball from you) Which is absolutely helpful cause i hardly had the CPU steal the ball from me using these suckers

Phantom fInery: (Can't be uppercut when ducken) I can't tell you how awesome this item is since you will be ducken a lot in the game. If you can get two of this for each player i say go for it!

Dunk Masters: (Dunking gives you 3 points) Again very useful item! even on game 4 but only give this item to the best player on your team who has a grade (A) dunk.

Plasma Chuckers: (Damages players with Molten plasma when passing the ball) It's not the worse gloves in the game but for useful when you need to pass the ball.

Fusion Core: (Regenerates stamina at a faster rate) which really comes in handy especially when you are you going to keep running from court to court. Like i said before only give it to the best player who has the best stamina.

Ninja Kicks: (Basically help you dodge incoming attacks then you normally would) Great shoes but i could of pick another Dunk master which would help me a lot.

So to the final solution/ Strategy i used. which you want to do is have Gwen dunk has much as possible but mixing it in with shooting on power tiles (Mostly on the stars, cash, energy, and Mega which is basically in the middle) using her specials can get quite tricky so i suggest using her charged one Giant Yarn by (Holding B) then tapping B to use her Ankle break special. She a lot faster when riding the yarn and extremely useful when it comes to uppercuts, blocking, and using her other ability Ankle Breaker since using it alone has a very small radius

For Frank you want to do the same thing but your going to do more shooting the basket then dunking since Frank has a good three pointer. His Special can be tricky too so i suggest you use only the jelly Jar and not the Berry Bomb cause you will hurt yourself only use the charge attack if you really need to just be careful not to get hit. So the timing for Jelly Jar can be quite difficult but with enough practice you can trap one enemy in a jar for a couple of seconds which really helps steal the ball from them,

I recommend using the Mega ability at the start of every quarter if do succeed on getting it each quarter which isn't really hard to be honest. i Had to run this game mode 4 times until i got the controls down and my last match i lost by one freakin point. Down below is my match, i felt like facing this two made it so much easier Obtaining the 4th win but sadly you might not come across the players i faced.



So in Conclusion i hope this sort of guide i guess i made lol will help you better achieving this achievement. The only hard part really is just beating game 4 since the CPU has way better items then you. If you down vote please do tell why just don't down vote for no reason. At the end of the day i'm the one here helping you out to get this achievement and telling you what method worked out for me.
