When I first read Peace and Thought, I was nothing but peaceful. Two heroes' actions used up for the round? That's insane! But I quickly came to realize the power of drawing a whopping five cards in one go. Here are its costs listed with some counterarguments:

The card slot - Seriously? Is that a concern when you draw five cards in replacement out of the deal?

A Lore resource - Okay, so you might have the tiniest smidge of trouble playing your piano hand. Either way, are you honestly complaining over five cards for just a resource. One for just two cards is a bargain.

Exhaust two heroes - Yeah, this is the big one, and the only thing keeping PaT from all Lore decks. This is a big price to pay, especially since you can only play it after your cards are ready for the round; no cheating it in after combat.

There are still a plethora of ways to mitigate the cost. Any sort of readying for your heroes rocket's the playability. In a multiplayer game where your buddies can cover for you or in a deck with low threat that can avoid early enemies, doubling your hand size is incredibly strong. The title is almost false-advertising. Just wait for the following planning phase, you'll know it when you hit it.
