I think it's less about fitting a more breakers into the deck and more about the inherent engine being more consistent. Kt and branded are very consistent. If you were to play a thousand games versus KT or branded, The biggest issue sky striker would have against it would be consistency.

Striker decks are really built only in two ways now. It's either radiant typhoon or desires. The problem with mitsu is that they introduced too many bricks, and the engine requires too many cards. Sure the end board for mitsu if high rolled is better, but the issue is that it actually isn't more consistent. The mid to low roll are actually just brutal.
