Brain Switch 1 - (CMC)

artifact

T, sac ~this~: Until end of turn, whenever player draw a card, other players draw a card instead.

Probably wording is a mess since it replace itself, any help for short working effect which wouldn't be self replace ?

Actually it can be used in any color, it can be easily recycled with quite powerful effect - opponent skip draw, and you draw instead so probably very powerful as 1 cmc. On the other hand each deck can play it and effect doesn't have big impact on game state - only on hands. I can see it could be very powerful with welder ;)
