How do cards than deny playing reactions interact with reactions that cancel card as it is played?
Cancellation goes in between announcing what the card does and resolving that effect.

B. Declare the effect.
1. Fully announce the effect (as applicable: the minion playing/using it, targets, cost, and so on). If the effect is a card, play the card to the playing area.
2. You cannot play a card or use an effect whose cost cannot be paid.
3. For cards, this step (II.B) is the "as played" window.
3a. Cards that can cancel a card "as it is played" can be played at this time, as can Wake-style cards whose effects grant the ability to play those effects.
3b. Other cards and effects cannot be used at this time.
3c. If the card is canceled, skip to step D.
4. For cards, your hand size is reduced by 1 until you replace the card (step D).
C. Pay cost and resolve effect (unless canceled in step B).
...
D. Replace the card (after handling all pending "as played" windows).
So if you play the card and it gets cancelled, it never has an effect.

"As played" (a phrase used by many card-canceling effects) comes after the card in question is fully announced and before the played card is replaced and before the effect the play generates. In general, no card or effect can be used in this window. The only ones that can be are the effects that say so, and Wake-style effects that enable such cards to be played ("may play reaction cards" effects, not "untap self" or other effects). [RTR]
