Id be looking to get a few of each when the regular nonfoil is at its lowest price, just for the Commander appeal
I created Curiosity and played with it against Lora
You can only do this once, so if you lose, you can only get the promotional card from the Challenge Cup After you have defeated your third club, then the Challenge Cup will open
All in all I was very impressed with how this deck performed, the unique game play experience it gave, and the fact that it made such great use of a lot of low powered and exotic cards
Id totally run it in a Charizard ex deck just to look extra fancy at my local events
Im absolutely only here to debate the merits of a unique card type in a trading card game with strangers online, so feel free to shout your opinions to my ever-willing ears down in the comments or over in the Draftsim Discord
