It was best to use this card with others that limit attacks Gravity Bind, Swords of Revealing Light, and so on
Its regular attack Subspace Swell can also do over 100 damage consistently without even trying to buff it intentionally, so that's a huge plus
If you happen to get 3 Guttersnipes and 2 Murmuring Mystics then you can slot all of those in your deck
You can use any Treasures on your battlefield to cast Deadly Dispute, Eviscerators Insight, or Costly Plunder
The joke here is that the creature of the same name in Final Fantasy XV is incredibly durable and takes hours to beat, but you're rewarded handsomely for taking it down (translated to Magic as Treasure tokens)
Meanwhile, Galarian Articuno can quickly attach energy and launch attacks on any Pokmon in play
