Is there any difference between double strike and oubleday ikestray?
Nop, it's the same.
Keep in mind, Atinlay Igpay is a card from the unhinged set. Meaning you can't normally play it except for casual play (and then usually you have to agree on it specifically).
The card is actually called Latin Pig in Pig-latin rules:

Juvenile &quot;code&quot; language created by the rearrangement of sounds in a
word such that the first sound is moved to the end and &quot;ay&quot; is added.
In the case of a vowel as the first sound, &quot;ay&quot; is simply added, with
an hyphen if necessary.

This is also how Double Strike turns into Oubleday Ikestray.
