Originally this was going to be a considerably more complicated land that was something like "reveal cards from the bottom of your library until you reveal a land card. this becomes a copy of that card UEOT". But I decided it didn't add enough over "it works/it doesn't work".
It would be more interesting if it was easy to get your main colour and harder to get your splash colour -- as it is, this is mostly "wait on average 1 turn". But I couldn't think of any easy way to weight it.
I'm not positive about the templating. I said "may" so it's hopefully more obvious you can skip the coin flip if you just want one mana and don't care about the colour.
You could make this higher-risk higher-reward by making it produce or but I think that would make it less fun and more broken.

Very nice use of "you may" to avoid the busywork if you don't need this to colourfix.
No idea if this is any good. I fear it is good enough for tournaments, which would annoy Spikes.
