Wizards of the Coast may have made a Magic: The Gathering design error when creating the Wilds of Eldraine set that allows players to combo for infinite mana as early as turn four.
The digital release of Wilds of Eldraine (WOE) on Sept. 5 has already revealed an infinite mana combo in the Standard format. Essential to the combo going off is Agatha’s Soul Cauldron, a two-drop legendary Artifact that exiles creatures from graveyards, adds +1/+1 counters to creatures on the battlefield, and gives creatures with counters all activated abilities of cards exiled by Agatha’s Soul Cauldron. Created by CovertGoBlue, and JRock from their chat, there is a Temur build that can pull off an infinite mana combo using Agatha’s Soul Cauldron by turn four.
