If you have one of those combos, it is easier to use some creature with a draw cards effect to find everything else, than adding more wincons (you just blink that with your wizard). That said, Temporal fissure might be an idea: you just play a few cards and this bouncing some of their lands and a return wizard (maybe more of your stuff to replay though) and do that for a few turns and you won. Besides that it is basically the same as capsize after the combo - just bounce your return wizard too to get the fissure back.
I would use the mana accel land auras, such as wild growth and utopia sprawl over the small elves. There are also more expensive options I would consider if you are really aiming for these combos. This way you got your accel AND your lands that tap for more mana.
You can also use frantic search and rewind+another return wizard for the combo instead of the creatures (rewind requires something to counter but on the other hand if you can counter everything they got, you do not really need more), if your lands produce enough mana. This may be important since the creatures are hard to find.

Merchant scroll may be a good idea for your deck as well.
