cunning wishing for traps

[TheRogue]

As everyone knows the traps cards have alternate casting costs. But if these traps are in the sideboard and the condition for there alternate casting cost occurs, would there be any complication to playing them by cunning wishing after the condition for the alternate casting has occured because the trap was in the sideboard rather than the your hand? i ask this because isn't the sideboard removed from the game? thus once the wish resolves it brings the card into the game and it wasn't in the game to (this is silly wording) witness the condition for the alternate cost.

The alternate casting cost for traps doesn't care if the trap was in your hand when the condition was fulfilled. If you look at Archive Trap, for example, it only looks if the opponent searched his library this turn. So you can certainly tutor (with Cunning Wish, Trapmaker's Snare...) once the condition is fulfilled. I know I've used Trapmaker's Snare to this effect : Path to Exile one of my opponent's creatures, let him get a basic land from his deck, then cast Trapmaker's Snare for Archive Trap + cast another Archive Trap from my hand for 26 cards milled.
