Morphling

Morphling is a ranged attribute-based gank carry that has many flexible skills and item builds. He has two nukes which he utilized very well to kill heroes in all stages of the game, which makes him quite potent compared to some other carries that only rely on their physical attack. His first skill is Waveform, which is a long-ranged blink that also damages anyone between morphling and the position. It is a very effective farming tool and nuke earlygame, and it gives him the flexibility to escape as well as kill. His second skill is Adaptive Strike, which is an interesting scaling nuke that damages, stuns, and knocks people back. The damage is based on his agility, and the stun and knockback is based on his strength. Lategame, it is very scary when morphling has a lot of agility because this nuke can deal much more damage than other spells in the game. His third skill is Morph, which allows him to switch around his agility and strength stats indefinitely - he can have 1 agility and all strength or 1 strength and all agility. It gives him a lot of flexibility with how strong compared to tanky he wants to be, and adds a great deal of damage to his Adaptive Strike. In the early game, it is leveled because morphling can change agility to strength when he is getting ganked, giving him much more health than he normally would have. His Ultimate, called Replicate, copies an enemy or allied hero, and this copy deals a significant portion of the original's damage, so it is useful with carries in the game. He can also teleport to it at any time, sacrificing it, which makes it a good escape ability.
