Every game you want to draw access to the "Sky Striker Ace" monsters, so playing 10 ways to access them is plenty. These can cycle every turn to gain advantage. The "Bystial" monsters both stops the "Tearlament" deck and provide niche ways to out opponent's boards. Ending on a "Sky Striker Ace - Shizuku" along with some backrow is usually plenty, as it allows you to search "Sky Striker Mobilise - Engage!" which gives constant resource cycling.
Even if you lose the first duel, you can still win game 2 with the variety of floodgates in the extra deck which can be used when going first, and board breakers to beat meta decks in game 3, along with the many going second options in the main deck such as "Change of Heart".
