Stalker vs Immortal

it may not be fast, but it doesn't need to when fighting the units it was designed to face, however, it will be pwnd by many other units

the stalker my be seen as the opposite, its blink ability will make it the fastest unit in the game with instant teleportation and would be harder to kill since a veteran player will teleport away when the battle is turned against them

 

Indeed so it able to attack air is fair! , just think about it
