I'm interested in trying these 2 -
Morphling
Adaptive Strike now has a 1150 speed projectile
Added Aghanim's Scepter upgrade to Morphling: Grants a new ability, Hybrid. Allows morphling to target an ally, turning himself into a hybrid illusion, removing the Morphling himself. This hybrid illusion can cast non-ultimate abilities and has your original attributes. Lasts 20 seconds. When the duration ends or the hybrid dies, your hero emerges (cannot end prematurely). Cooldown: 140, Manacost: 200, 600 cast range. Note: Ability is not available while you have a Replicate living.
