Collectible Card Game Headquarters

Hey, I'm still somewhat new to MTG, but an AI player played this card. It is a 4/4 green white with the text

"other green creatures you control get +1/+1" and
"Other white creatures you control get +1/+1"

When the AI played it, I don't know if the "other" keyword is properly implemented, because the creature entered as a 7/7 creature.

I would think that "other" wouldn't target itself, but maybe I'm misunderstanding the word in this context?

Thanks.

Hmm, there must have been something else going on with the AI deck synergies that I missed. I just found dev mode, and adding the creature to the field provides the proper effect.
