This trophy requires you to get A-Rank or higher on King Dice and The Devil.Recommended loadout and strategy:

King Dice

• Shot: Roundabout/Peashooter + Spread (against King Dice)
• Charm: Smoke bomb
• Super: Energy Beam
• Number 3/5/7 mini-bosses are highly recommended when using the Smoke Bomb

You need to learn how to control the dice and use it to your advantage. Duck under the dice and quickly double-tap  just before the number you want. Another method is to jump 2 numbers before the number required and parry the dice after 1 second of jumping.Let's start with boss NO. 3 the cigar, use the peashooter or roundabout, dodge the fireballs by moving away from the middle of the screen then moving back to the edge, and smoke dash to the other side when the cigar changes his location, use special moves to knock him quicker.

Boss NO.5 is the magic rabbit. Stand on the middle card and keep shooting at him, smoke dash through the skulls when they start closing at you. jump and parry the pink heart when the row of face hearts comes from the bottom and use your super move to give you invincibility temporarily when the row is coming from the top.

Boss NO.7 is an easy boss with the smoke bomb equipped, just shoot her while smoke dashing through her legs, when she starts throwing the white balls just dash away from the center. Fill your super meter and save it for King Dice. Keep shooting your peashooter and she will go down in no time.Finally, you get to fight king Dice. For this fight use the Spread and stay in the middle to avoid getting hit by his hand, once his hand on the table go to the other side, a bunch of cards will come out of it and you need to jump and parry the pink cards to dodge them and to do the 3 required parries, use your super energy beam when all the cards come out. Keep shooting with the Spread but use the peashooter special move on him to do more damage. repeat the process till you knock him out.The Devil

• Shot: Roundabout (phase 1 only) + Spread (phase 2,3 and 4)
• Charm: Twin Hearts
• Super: Energy Beam

For the first phase, you will be using the Roundabout all the time so you can focus more on dodging the attacks. These attacks are:

• 4 balls including one pink ball that you want to parry
• He will attack using his head as a dragon and comes from the left or right, stay in the center to know which direction he will come from then go to the other side.
• A pink flame that can be parried with blue flames around it, parry the center flame then dash away.
• His head might transform into a spider, dash just when it appears on the screen, and Not before you can see it.
• Clapping his hands in which you need to jump and dash to stay in the air for a longer time, it's a bit tricky but you need to master the timing right.

The second phase is when he takes off his cat Clothes/Skin and turns into a skeleton. Use spread on him before he jumps down then jump down into the hole after he jumps. Stand on the 2nd to the left platform and use spread from now onward, jump one time when the Axe loop around you and comes from below. Only change platform when the poker chip is dropping on you, you should know that the poker ships do drop from either left to right or right to left, one platform at a time. Parry the pink bombs and use a super to finish the phase quicker. In the third phase, get rid of the purple animal to your left and keep shooting at the boss. Don't shoot the other animal because that will make them spawn much faster. Move to the middle platform to avoid the poker ships then go back to left one. The last phase is when there is only one platform and you have to dodge a poker ship too. All you can do is jump away and go back to the platform as fast as possible and keep shooting till he gets knocked out.
