The upside is interesting here, and in many EDH games, you should be able to mill 25+ cards with Space-Time Anomaly alone
The only drawbacks here are that it's limited to 2 card types and goes on top of your library instead of in hand
Learning to effectively combine cards can lead to powerful moves and possibly decisive turns in matches
Chances are its going to drop a good chunk, though
