Striker already has the ability to break boards reasonably well which is a big part of why Striker Tenpai exists. The issue with pure Striker in MD is that modern decks set up a ton of followup so when you barely break through their board they're easily able to deal with the set Widow Anchor+Shark Cannon+Raye in GY.
The new stuff lets them both set up more interruption to deal with the followup turn and more recursion for themselves beyond just relying on the opponent letting you use Raye's GY effect to add back Engage on their turn.

Also this card+MST has become standard in the OCG. Obviously any bonus draw power given to Sky Strikers is a big deal since I'm sure we've all had situations where you have them down to one card and suddenly they go Talents draw 2>Upstart>Engage>Engage>Upstart>Engage>Kagari>Engage
