{Rakdos keyrune} if thats been in play for more then one turn does in suffer summon sickness to be a creature?

[abstractApathist]

No: as long as it has been under your control continuously since the start of the turn, it will not have summoning sickness, even if it didn't start the turn as a creature.

Cool thanks, is it the same for lands that get turned into creatures by sorcery or others? Basically if i have a card on the battlefield and it gets turns into a creature and ive had it since the start of my turn, its not bothered by summoning sickness?

[Pleeb]

Correct. Summoning sickness only cares if the permanent has been under your control since the beginning of your turn. Everything else is irrelivent.
