Fraying Sanity's triggered ability counts the number of cards that were put into the enchanted player's graveyard during the turn, even if Fraying Sanity wasn't on the battlefield at the time those cards were put there, and even if those cards have left that graveyard
Cards like Zombie Cutthroat and Gathan Raiders made it impossible for players to block or attack into any morph creature for fear of losing the combat without a fight
Its a simple ability on the surface, but its one that changes the combat maths of the game drastically and gives you the survivability you need to get into the late game, where you can leverage your mushroom minions to inflict unstoppable lethal damage on your foes
Is it fun to actually pull off a combo in Lorcana
Were at what Id call the mature end of the format, with the largest and deepest card pool possible all on the table to tinker with until the Ravnica sets and M20 rotate out in a couple months
dont wrath in the late game unless you are capable of turning things around and have a game plan
