In the Star Aligner mirror, the person who gets DK Malfurion first wins. This shows perhaps the preferable way to combo your opponent is through an inherent advantage rather than an OTK [one-turn kill].
This 'proves' Star Aligner's inferiority to other slow druid archetypes. Togwaggle Druid does not self-buff but rather debuffs your opponent's deck. Jade Druid...buffs Jades [not the same thing as an inherent advantage]. An inherent advantage or a recurring advantage is the preferable way to combo your opponent.
