{T}: Add one mana of any color. You get two poison counters.

{2}: Add one mana of any color.
Other noncreature artifacts are mono and continuous. (Each activated ability of mono artifacts costs an additional {T} to activate if its cost doesn't already include {T}. As long as a continuous artifact is tapped, it loses all abilities.)

Instead of taking turns as normal, players take their phases sequentially. (For example, you take your beginning phase as the active player, then the next player in turn order becomes the active player and takes their beginning phase. After each player had a beginning phase, do the same for first main, combat phase, second main, ending phase, and then beginning phase again. If this creature leaves the battlefield, the active player continues their turn as normal.)
