Actually, since all wagers are Swifts unless stated otherwise...

Round 1: Wager to build burn
Round 2: Cash Out
Round 3: now you can use those temp PPs.

The round 1 wager may cost you PPs as well. So you're pretty far from "all day blasting", and you aren't gonna be adding any riders to your blast before round 3, nor getting any free casting before then.
