Kite Riders provide additional flexibility and extend the Storm Goblins' reach. Their solid health allows them to block key summoning spots or strategically trap the opponent's Summoner.
While less essential than Voltswappers, Kite Riders offer versatility, providing extra reach and inexpensive blockers wherever needed.
The Lightning Strike ability is situational, with some marginal uses. For instance, it can be triggered by attacking a gate, but this might also damage the Kite Rider itself.
