Sort of.

You'd have to run the server yourself to be able to use bots.
Then you'd have to start a multi-player game between you and two AI players.
Then you'd have to concede the game immediately.

This is almost the same, with slight differences such as that everyone gets to draw a card in the first turn.

I think you'd have to start every game yourself since you have be in them, but multiple games can run simultaneously.
They are very resource intensive though but they will run fast.
The AI is not a good player though and will make some dumb choices, especially in complex decks.
Such as using Deflecting Swat on a Lightning Greaves, either the spell or the ability.
