In Yu-Gi-Oh: could you activate a monsters effect the first turn you set it down?

Question

What about kaiser sea horse?

Or guardian statue as well as sonic bird?

Answer 1

noooooooooo

Answer 2

Yes, some monsters have special effects which allows you to use it right away.  Im sorry for those 3, im not quite sure

Answer 3

Kaiser Sea Horse is a no.

Guardian Statue is also a no.

Sonic Bird however, you can. Because it says "when this card is summoned", so when you play it, it's effect activates!

I hope i helped!

Answer 4

yes when you summon it you can activate its special affect but look out for ur opponents cards he may be able to stop it
