TappedOut's April Fool's thing is amazing.

I suggested this, she said she still needs to pick them up (and I can loan them out since I'm running LOL STANDARD EGGS this week for funsies). Can also loan out a Drowned Catacomb and Dragonskull if you want/need more flexible mana (to replace one island/mountain).
re:boardwipes. Mortars does deal with Smiter/Resto though. I would also suggest Mutilate, but you only have 8 swamps, which is a problem. Cyclonic Rift? Yes, it only bounces, but if you can control to 7 it can work very well. Also instant-speed, and can remove planeswalkers or other specific troublesome things on their upkeep. Not to mention if you draw/Augur a counterspell a few turns too late, bounce->counter is always fun.
I would personally run Brimstone as a 2-of and up Spear to 4 or mainboard the other Rakdos' Return, since it's only better than Spear upon Morbid trigger. You have very limited ways of hitting that (Bonfire, Spear, Izzet Charm mode vs Naya Humans etc., Dreadbore - 7 or 9. Or suiciding your own guys). If you're using it for Morbid-removal, use Slip.
You can also drop all three and up your Delver/Augur to 4. I'm surprised you're not running all 4 actually, since Delver is a great turn 1 (although a terrible topdeck) so you always want it opening hand, and Augur not only blocks aggro T2 but gets stuff in your hand for both control and Guttersnipes. I'd suggest that, personally: -3 Brimstone, +1 Delver +1 Augur +1 Spear/Return. Probably Return, but -shrug-. You could also drop the Delver completely, and a Brimstone, and have two extra card slots. Limits your damages though and means you have to deal with relying on Olivia/Dragon/Guttersnipes for damage.
[edit] Think Twice is a fine card. Instant-speed card draw plus flashback is amazing flexibility: perfect for control. I didn't like it when I first tried it out (towards the end of Scars rotation) but I've grown to appreciate it.
