Of planes walkers suffer the the sickness of the summoning??? My mate i test deck with says they do, but just though I should ask here, as everyone seems to know stufff
Planeswalkers can do a loyalty ability the turn they come into play, at sorcery speed (during your main phases and nothing on the stack)
However if one of the abilities (or something else) makes it a creature then unless you give it haste it will have 'summoning sickness' until the following turn.
The last/first thing to remember us that only creatures have summoning sickness. :)

Thanks, XD
Gideon human form does suffer summoning sickness in regards to attacking but not in becoming the human
