The Madcap Jester

It needs four mana, an untap, and combat to gain a random card, below Modern's 20-score Skateboard benchmark in immediate impact and efficiency.

Could be wrong if An unusually efficient library-exile combo shell could use its broad permission to cast exiled cards, though none is supplied.

Four mana and an attack step are far too delayed for Legacy; unlike 47-score Consider, it offers neither immediate selection nor protection.

Could be wrong if Fast mana could deploy it early, but its fragile body still needs combat and is vulnerable to abundant cheap interaction.

As a Grixis commander, each attack can access up to three opponents' top cards through the next turn, a substantial repeatable value engine; no haste and 3/2 stats limit it.

Could be wrong if Random opposing cards may be unusable or too mana-intensive, and opponents can repeatedly remove or block the Jester before combat.

An attack can yield a borrowed card, but UBR for a 3/2 and a one-turn delay make it merely playable, near 45-score Aang's Defense rather than premium.

Could be wrong if Unknown fixing, speed, and removal density determine whether its demanding cost and fragile attack trigger are realistic.
