Here, my primary concern isn't speculators or collectors but the poor college kid on Reddit trying to put together a Modern deck that ends up with fake Mox Opals off eBay, or the new player who thinks they are getting a good deal on some Modern staples to build their collection off Craigslist and hasn't played enough Magic to realize the cards are fake
Since the Rose Tokens get summoned to both sides of the field, this effectively means the player can destroy their opponents monsters as well
Use one red mana to activate Voltaic Key to untap Prototype Portall, and copy the trigger with Kurkesh, Onakke Ancient to untap Voltaic Key with the remaining red mana
Speaking of Zapdos and Articuno - they have Rocket cards too
You can only pull an Enchanted from the foil slot, and these are by far the hardest rarity to get
Theres an abundance of ways for you to untap Szeras and sacrifice a few creatures in the same turn to generate a ton of mana since its an artifact, but those creatures need to have cost a lot in the first place
