Its got many applications and combos, but you can keep it simple and enjoy double triggers from legendary cards like Loran of the Third Path or Ao, the Dawn Sky
However, after a mediocre performance at the last #SCGINVI with G/U Infect, I feel like the metagame is too hostile to play that version right now
With the sole exception of occasional hole filling design during development, cards are not designed to a particular metagame
If you're the defending player, Kazuul's ability triggers once for each creature that attacks, not just once per combat
or an ability like kicker, which lets you spend mana to do something else, you still have to pay those costs
Even so, this enormous body and tiny cost feel undervalued at $1-$2, which is why I'd be more aggressive with picking these up
