Your observations are mostly correct, except for damage on stack. Unfortunately, damage no longer uses the stack.
An impo trick though is try to resolve high tide in your opponents upkeep before they draw an extra card which could be countermagic.
I don't run Words. Its bad. If you are in a tight spot, for instance, lots of land and Forces post-meditate(s), Wish for Tolarian Winds, and continue your chain. It works wonders and has won far more games than you'd expect. There aren't many situations in which I'd find Words instead of Meditate.
The combo matchup is actually fairly good. Remand becomes really good in that sure your opponent gets back his business, but its pretty irrelevant if he can't ramp back into it. Post-board, Mind Break Trap wrecks them.
This is the list I play IRL. I recommend it over the versions with FoIn and Cryptic Command. Peer does the same job as FoI but finds cards while you set up. Cryptic Command is just bad. At 4cc you I've extremely rarely hit enough land drops for it to be playable. I go off pretty consistently on turn 4 with this list.

Btw, I don't know if anyone has been keeping track of the new set, but Mark Rosewater has told us that there will be a Draw 3 for U with some sort of draw back. If it turns out to be an instant than I think it could be playable.

What drawback could it be? Even if its something as 'bad' as skip your next turn, its more certainly playable in solidarity over something like Opt.
Discuss.
