Bruh this card is broken wtf. Might be the best Vehicle I’ve ever seen. Crew 1 6/5 is already pretty good, but it also has the potential to make massive amounts of treasure tokens very easily.
I don’t know about you, but in Pioneer I play Gruul Vehicles and I wouldn’t pick this over Esika or Skysovereign.
Broken in what format? It’s 5 mana and does nothing without a board presence. It also has to attack to make the treasures, so you could get blown out if you crew and then it gets killed before declaring it as an attacker. I don’t even think this is broken in limited.
Blowing it up after crewing before attacking would be a good way to deal with it. If you have some defensive spells you could protect it while it attacks for a couple turns. In the right deck you only need to trigger its power once to get huge value from it.
