Ultimately, the best commander is the one that makes you smile

As a broad rule of thumb, somewhere around 8-10 spot removal spells is a reasonable amount to play in your Commander deck

The Treecko and Mareep both have their respective set stamps, so I assume the Dratini has the same treatment going on as well

The only matchup I can think of where the benefits of shutting the opponents mana off potentially outweigh shutting off my creature lands is U/W/R Control, and even then this lets them use the Tear side of the Wear // Tear they usually bring in (assuming they are smart enough to fetch out their basics early on)
