She isn't even limited by when you can do with it
Dragonspear - 1W - Artifact: Equipment - Choose A Job (When this equipment enters create a colorless 1/1 hero token and attach this to it)
The artwork provides atmosphere to spare, too
When you do, put a +1/+1 counter on that creature
However, since I dont want to go through all the ways green can do this (mana elves, doubling effects), Im limiting this to noncreature cards that put lands into play from your library and are green (there are some white and colorless ones that do this as well)
I actually think it made things interesting to have four of us in green, since good green cards are so deep for Commander, but there were certainly cards at the top of the list that everyone would want to nab
