one piece new booster box TCG - EB02 part of the OP The Time of Battle Booster

By exerting this card, players can take a look at the top two cards of their deck and then return one to the top of the deck and put the other at the bottom of the deck

Either way, after the madness card is cast and leaves the battlefield, it goes to the graveyard like a normal card

Faithless Looting (red, 1 mana): Draws two, discards two, with flashback for a second use

Reliably getting a known number of 1/1s is far more helpful in terms of planning than "the best thing in play at the time"

Do any of these class cards call to you

You can cast instants whenever you have priority, but a sorcery with flashback still has to follow the sorcery speed timing (in your main phase, whenever you have priority and the stack is empty)
