Throne of Eldraine Missed Triggers Guide

Edited Beau (Oct. 1, 2019 07:52:09 PM)

Hello again, judges! The Missed Triggers project is back with an update: Murderous Rider has been moved to “generally detrimental”, from its previous assessment. This card was the subject of debate even before the set released, and after a month of seeing it fielded, opinions among judges and players strongly align with the new evaluation. A more in-depth explanation can be found in the Throne of Eldraine guide, but the simple version is:
(1) This card is easier to access from the graveyard than from the bottom of the library, which means (2) that the conclusion of the “vacuum test” is a weaker argument than usual; it's not enough to outweigh the fact that (3) players will nearly always prefer this card being in their graveyard.
