As far as counterspells go, I like:
Counterspell—It does exactly what you want a counter to do, but the restrictive mana makes it less "simply the best" than it is in Constructed, so there's some small amount of interesting tension there
Mana Leak—Better than Counterspell early, worse late, easier to cast. Someone on here wrote a novella about the positive effects Mana Leak has on Game 2 after you Mana Leak in Game 1 so that's cool
Remand—Draws a card, buys you time in control, stumbles your opponent in tempo, and you can use it on your own spell once in your lifetime for an AMAZING BLOWOUT. Also funny against flashback spells if you have any of those worth countering
Memory Lapse—Sort of the negative flip side of Remand, gives you more tempo gain but probably slightly less card advantage than Remand, depending on whether your deck or your opponent's deck has better draws (it gets better the better your opponent's draws are)
Miscalculation—Seriously why has this not been reprinted in a duel deck, I want to run it in my Modern-frame Cube. Cycling is just the bomb and most decks don't care that it's 1 worse than Mana Leak
Dismiss—It's like the half of Cryptic Command I'm not too much of a scrub to know when to use, but less than 1% of the $$$ (unless you proxy). Wheels to the control player, just like I want it to, and isn't as tough on the ol' mana as Cryptic
I probably forgot a few of my faves but that's my thoughts on counters.
