Thanks for the replies guys. 
Normally I use a red D6 on top of my library to remind me to ping my opponent with my lands before I start my turn, but I recently got a copy of Koth vs Venser so now I have the proper Emblem as well.
the rule is somewhat vague on what a ''small object' is.
Isnt it anything small enough to not complete obscure the top card?

That's not what it says, so we can't say one way or another how big a small object is.
To some people, a loaf of bread is a "small object". We can make up our own definitions based on what we consider reasonable, we can even agree with each other. That doesn't make it correct or incorrect though, since the description is vague. Ultimately, if you and your opponent can't agree, it will be up to a judge.
