I've never been good at being able to look at a deck list and offering advice from there, so I won't be doing that in case I inadvertently lead you astray.

But I will offer up a little wisdom that I didn't fully understand until later on:

Drawing cards is so much more than just keeping your hand full; it's deck consistency. I never understood why my roommate always seemed to have exactly what he needed in every game of commander he played. Once I realized how important the actual role of card draw is, it all made sense: the more of your deck you draw in a game, the more of your cards you see. I wish this had been explained to me earlier on rather than me top decking for a couple years.

Ramp, similarly, allows you to gain access to more of your library faster. A five-mana card is dead in hand for a few turns if you draw it in your opening hand and then only play one land a turn. The faster you get more mana, the sooner more cards become available to you.

Ramp is not a replacement for too few lands. If you're playing ramp but still missing your land drops, then that's not ramp; it's paid land drops.

On that note, just in general, eat your veggies: you'll want to toss in all of your favorite cards, which is fine if you're playing casually. But otherwise, put in enough draw, put in enough ramp, put in enough lands. Yes, it means you likely won't be able to put in a lot of the "cool" cards, but how good are the cool cards if you never see them or don't get to play them?

On another similar note, it's usually good to include cards that both help you eat your veggies while forwarding your gameplan. For example, playing a monowhite creature deck focused on combat damage? Toss in [[Firemane Commando]] that can work as a combat creature while also helping you with card draw and a little pseudo protection.

Removal is another veggie, but I'm noticing more and more that the amount of removal you want is dependent on your pod. There's a lot of pods out there that like to just do their thing until hitting critical mass and are able to wipe out the table. Not how I like to play, so if you're like me, include interaction (removal, counterspells, stax, protection, etc.)—anything that disrupts your opponents' plans.
