Zur’s Weirdering

Reveal this Conspiracy only during yours or a teammates upkeep
When this conspiracy is revealed, untap all lands
and empty all mana pools. Until end of turn,
players play with their hands revealed. Players
can play cards from other players hands, cast
spells as though they had flash, and spend mana
as though it were any color. Players can't play
cards they own this turn.
