This is the mark of an overpowered card. When you look at Tickatus in the same light, it isn’t remotely close to achieving this.
Evolve shaman was (and still is, in a lesser manner) a super-tempo fast deck (similar to aggro, but still not it exactly, even though the damage output by turn 6 is similar), effcient against a wide range of decks and archetypes, Tickatus warlock is a control deck that fares well against other control/combo but poorly against aggro. Meta is and will always be leaning heavily on aggro, given how it's dictated by F2Players. So... do I need to state the obvious?
