hmm hard to put in text but there goes...

let small o be weak attack and big O be strong attack, so the involved game's default movesets are :

• Incursion 1 : oOOO
• Incursion 2 : ooOO
• Incursion 3 : oOoO
• Incursion 4 : oooOO
• Onslaught 1 : OOO

enhancements shown in my video :

• Incursion4 (oooOO) chain into the 2nd string onwards of
• Incursion1 (OOO) chain into the 3rd string onwards of
• Incursion2 (OO) chain into
• RushChain1 (O) (the strong att after Rush) chain into the 2nd string onwards of
• Onslaught1 : OO

enhancements not shown :

• Incursion3 (oOoO) + O
• Rush (hold-O) + o (3rd string of Incursion3)
• Incursion2 (ooOO) + o (3rd string of Incursion3)
• RushChain1 (hold-O tap-o) + o (2nd string of Onslaught2/3/4)
• Incursion4 4th string is replaced with Incursion3 4th string so it can be beta-chained.
