When Mindsplitter is played in a multiplayer game, is the revealed hand shown to only the casting player or to all players?

Ruling: The revealed hand is shown to all players.

Nuances:

• If the card were intended to show the hand only to the casting player, it would be templated differently (e.g., "when you play me choose an opponent. look at their hand. choose a card from among it, and they discard that card")
