Can u tap black lotus as soon as u cast it on the feild? Or does have summining sickness
Only creatures are affected by summoning sickness
{Izzet Cluestone}, {Sol Ring}, {Darksteel Ingot}. You can tap all those sorts of things right away.
{Copper Myr}, {Elvish Mystic}. Those are creatures, so they have summoning sickness.
Just to clarify, an {izzet keyrune} could tap for mana the turn you played it. HOWEVER, if you were to animate it first, it would then be a creature, and have summoning sickness and not be allowed to tap for mana.
