I need to play rogue cards and odd rogue is the only viable rogue deck at the moment, but I don't have this card.  Is there something I can replace it with that is as good?

Ofc not as good. If you replace, it will be considerably worse, although possibly acceptable.

Sprint is what resembles UA the most. Ofc, not as good if you use it to gather your finishers.

Depending on the list you are using, you could also consider Mimic Pod, Raiding Party (if you use 5+ Pirates), Acolyte of Pain. They are less impactful than Sprint, but they are more efficient, so you can use them in mid-game.

I am using the list from Tempostorm.   It has two pirates, so Raiding Party is no good.  Sprint seems much worse (2 more mana, ~10+ fewer cards).  Mimic Pod is at least cheaper, but you only get one card.  Would my list be viable with either of these replacements?

There is NO card that replaces it.  Sprint is way too slow, and doesn't do enough.

Run any odd costed card that fits the archetype.  Possible choices:

• Cobalt Scalebane (2nd copy)
• Void Ripper
• Blink Fox
• Blood Knight
• Snapjaw Shellfighter
• Captain Greenskin
• King Mukla

Note that all of these cards have been used in various Odd Rogue lists in the past.

Just run another minion (see post above). Also there are more viable Rogue decks than Odd, they are just not as well positioned in the meta. Tempo Rogue is really fun and pretty decent.

I tried tempo rogue, but it runs out of cards too fast even against the weakest decks.  I think odd rogue is the way to go.  It's just everyone netdecks the most powerful meta decks identically, so it's really hard to have a hope unless you do the same,

Myras is like the strongest card in odd rogue and tempo rogue.  If you like those decks it's very craftable.  

You can't replace it's effect so just put another good five drop.  I like snapjaw shellfighter because it's funky.  Greenskin could help give a tiny bit of gas since you lack Myras.

Personally, I like running a "bulkier" version with Tar Creeper and Spiteful Smith.
