Lacon, Dragon Caller

Only one spell of each color may be played each
turn unless it is a dragon spell.
Dragon spells cannot be countered and dragons
enter the battlefield with an additional +1/+1
counter on them for each color among
permanents their owner controls.
{p/w}{p/u}{p/b}{p/r}{p/g}: Lacon, Dragon Caller loses all
abilities until its controller's next upkeep.
Any player may activate this ability.
