The only black bordered 13 Mana Spell - Emrakul, the Promised End This card makes me think of the Eldritch Moon Pro Tour
Thought Vessel Oh look, a Decanter of Endless Water that costs 2 but only taps for colorless
For example, a given property may or may not have elves, and this type of worldbuilding impacts reprint selection
I especially enjoy building around more expensive legends to fly in the face of the narrative that Commander has gotten too fast and efficient these days to play something that costs eight mana, especially outside of green
But in the older days of Magic , cards like that would stay in the graveyard, where theyre ripe for abuse
Its swingyyou might crash out early or score a flashy winbut either way it creates wild table politics
