Help with standard red/blue deck

[Inconnu]

So what I need is a legal card, ideally with easy casting cost, which could be used in a blue/red comtrol deck to sac creatures I grab temp or if opponent tries to destroy or grab back.
I have fling already plus trying to get the cards for exile/keep control.
Suggestions from the collective MtG brains here would be great.
Thanks.

Mortapod

{mortarpod} does the trick.

{Skirsdag Cultist} too.

{culling dias} is another option.

{Ghostly flicker} makes it yours and saves it

Forgot about that trick, I'm so used to seeing with white only because of {cloudshift} and its abundance of flicker.

{conjurer's closet} will work also

Card Database > Search by text "Sacrifice creature" > {U}, {R} Exclude unselected > Format "Standard"

Voila!

[Inconnu]

Those will work.
Thanks for the hints.

Do counterburn!!!! {Stuffy doll} + {Gremlin Mine} + counter spell/draw spells + burn spells! Stick maybe a couple {Curiousity} in to help rather than a draw spell
