Similar to Mythic Rares in Magic: The Gathering , theyre not guaranteed in any booster pack you might pick up
For the card, we wanted to lean into the joke, so we made the back face a legendary Serpent
You can only use each effect of Curse of the Ancient Turtle once per turn

This deck is weak to countermagic and similar interaction Game 1, so it makes a lot of sense to transform into the older creature/planeswalker plan, and I believe Glorybringer to be a great way to facilitate playing fair. Creatures (17) 2 Ayli, Eternal Pilgrim 2 Archangel Avacyn 4 Thraben Inspector 2 Thalia, Heretic Cathar 3 Sram, Senior Edificer 4 Walking Ballista Planeswalkers (4) Lands (24) Spells (15) Probably my most boring deck today, but I think it showcases a valuable lesson
