what does gold star mean on pokemon cards Alakazam - Crystal Guardians The 10 Most Expensive Gold

At the end of the event it was Mono Blue Terror that won

There are two key differences here that you can rely on

Its that easy to identify an activated ability

A 6/4 with flying and trample for seven mana, Atarka states that whenever a Dragon its owner controls attacks, it gains double strike until the end of the turn

While some might think mono-blue for control, the addition of black gives players access to creature removal like Soul Shatter and Professor Onyx

I think the fact that Inquisition of Kozilek is more limited in scope this way definitely makes the card more interesting, but its universal enough that it helps alleviate Moderns historical issues around having too many narrow disruptions spells
