"I want to recommend the devil Sky Striker Ace" Deck 2018

Playing

should take the lead. If you go second, you run the risk of your opponent playing a strong monster or dealing with a face-down card.
《Ash Blossom & Joyous Spring》, 《Ghost Ogre & Snow Rabbit》, and Proliferate G are scary, but I don't think there are many people who use them on the first turn. (Even if it is activated, it is OK if you think that it was used in the early stages!)
Engage → Search Hornet Bit → Summon Sky Striker Ace Token → Link Summon Sky Striker Ace to Kagari → Recover Engage with effect.
Collect Engage in hand as above and prepare his required Sky Striker card in hand.
(example)
Afterburner, Widow Anchor
Since 《Hayate》cannot be used in the first move, I link summoned 《Kagali》to 《Shizuku》in the main 2, and in the end phase, I add his Sky Striker card to my hand, which was not obtained by 《Kagari》.
The basic movement is like this.
If there is an engagement in the first hand, I think it will go around quite a bit.
Diabolos can only perform Special Summons from his hand and GY, so if he drops it with 《Foolish Burial》and releases it with the effect of [Ray], he can also Special Summon from GY, and furthermore with the effect of [Ray]. It is also strong to bring his Sky Striker Ace from extras.
Also, after the Battle Phase, it would be nice to be able to use Diabolos' effect to open up the main monster zone and turn his Sky Striker card.
Also, his Sky Striker card has the effect that if he has 3 of his spells in his GY, he can use more abilities, so 《Toon Table of Contents》is a good match for this effect.
If you use 《Toon Table of Contents》, you can quickly drop three cards from 《Toon Table of Contents》to 《Toon Table of Contents》, so don't hesitate to use it if it's your first hand.
By stealing the opponent's monster from his GY with Shark Cannon and selecting it as a destruction target for multi-role, you can protect yourself from hand triggers without losing yourself. (Even area zero is OK!)
As for the Shark Cannon, why do I have two copies? Recently, he has increased Special Summon from GY, so I put it in to exclude the monsters that can be revived by Shark Cannon.
For example, if 《Blue-Eyes Alternative White Dragon》of the Blue-Eyed Deck is revived by 《Monster Reborn》or 《Return of the Dragon Lords》, it will be troublesome, so let's exclude it.
When I tried using it on my friends, I was glared at with a terrible face. It's funny.
It's generally like this. After that, please try to understand Sky Striker Ace better by thinking for yourself or watching other people's play.

Strength

Deployment power using engagement etc.

Weakness

Sky Striker Ace doesn't have much firepower.
Too much expansion will clog up later.
It ends when the Deck is destroyed.
Since the effect of targeting is general, it is difficult to remove monsters that are not targeted by the opponent's effects.

Customize

I don't think so.
It may be a good idea to add 《Solemn Warning》, a declaration, etc. at your own discretion.
Well, the point is, I feel for him. Try it once and change it if it doesn't feel right. I think it's good for him to come up with a deck through trial and error.
