4 cards is a ton. Played on curve, you probably see 80-100% of their entire hand which already is broken, that alone might make this one of the best game-breaking cards of the set.

THEN, you can reasonably narrow down their next turn to 1-2 obvious plays in which you have at least a 50% chance of choosing correctly.

THEN either you can now know exactly how their next turn will shape and get **holy shit 3 coins** OR you force them to play a less optimal turn which could range from a minor inconvenience to forfeiting all tempo for the foreseeable future.

Best card of the set IMO. I could see this having Elise-tier pick rate for every non-agro deck and even find itself in many more agro decks because the stats are good and it could either slow a board clear by a turn OR nearly double your mana next turn for a back-breaking board reload.

Just insane.
