There are so many great replies in here that I am hesitant to even add my own.
I am a believer in using proxies if you own the card and it is an expensive staple. For example, I own one of each fetch land, especially thanks to Khans and Modern Masters 2 or what ever set it was. I keep them in a small binder with other powerful staples I proxy in multiple decks and can show them if needed. Having fetch lands changes the game. More so since check lands were printed. It took me a while I get my hands on them, but in my three and four color decks, the play line which involves a fetch land into a shock land and following that up with check lands is smooth. I cannot justify the cost of a full set of fetch lands for each deck, nor do I feel I should punish myself and only use them in one deck, nor do I want to swap them in and out between decks either, which I could and would just waste time. Especially for a kitchen table format without prizes.
Lands are the perfect example of where MtG is "pay to win". Sure, you can use cheap commons and slow play, or use a ton of basics and suffer color screw, or you can buy expensive singles from the secondary card market and have a fast and smooth experience.
So much of what I wanted to write was some variation of all the above, be it our holistic detective, Pokken the cat and others.

I personally dislike proxies and refuse to play with them. But that's just me. This is a good solution that I have seen by many people.
You're playing 2 colours; i highly doubt you need to resort to comes into play tapped lands. you're time-walking yourself. I think it was my hannah, ships navigator deck that runs 30+ basics, split about half-half. I can't recall the last time i was colour-screwed.

But think about it this way; how important is it to you to be able to say:
turn 1 swords to plowshares
turn 2 counterbalance
turn 3 ponder into eight-and-a-half-tails?
if your deck doesn't have that sort of really mana intense and low curve for your deck to work, then it really doesn't matter all that much.
I only have 1 deck that can be so colour intense, but none of my EDH decks function like that.
