Two headed giant help

[Richardalcala]

Hi guys just trying to figure out a good deck for my buddy for two headed giant. If I have a creature in play that gives like creatures bonuses does that count for his creatures. Could I give his creatures counters as well. Thanks.

It's all about English grammar of text. If it says all goblins get +1/+1 then all goblins get the bonus. If it says your goblins then your friend is out of luck.

Ok thanks for the help.
